Okay so here is a summary :
Chapter 34:
I starts with a really short flashback of Takayuki talking with his father (Takamasa), trying to know who are Katsuragi's parents, then Takamasa say they will send Tomoyuki to the Kuze house so that no one will ever know his origins (the poor boy ;___;).
Back to present, Akihito is determined to go talk to Takamasa to know about Tomoyuki's real origin (yeees boi) and once he arrives at the Katsuragi's house he asks Takayuki to let him talk to the old man (Takamasa). While Amamiya is in a horse-drawn carriage to bring Tomoyuki back to the Ishizaki house and he notices all the hickeys Tomoyuki has and it was really funny lol
Both of them are determinated to do what they think are the best for the other.
Chapter 35:
Tomoyuki's side : he is talking with Soemon, Tomoyuki says he is back to his "old self" (he isn't someone who obey to others and don't care of others' opinion). They talk about the clothes facotry(????) and then talk about Akihito. Soemon "reassures" him saying he actually appreciates Akihito (who is really different from his father). And Tomoyuki says he belongs to the Kuze family and that his life is Akihito's (kyaaa >_<) after Soemon saying he wanted Tomoyuki to work for him until he dies.
Then Soichiro meets Tomoyuki and discovers Tomoyuki was dismissed from his function as the head clerk of the Ishizaki family (gosh was this sentence correct XD). And Tomoyuki is concerned for the people who work at the factory.
Akihito's side : he who argues a bit with Takayuki who didn't want to let him meet his father and says it's a lost cause since his old man is sick as hell and can't even talk. But in fact once he opens the door the old man is doing a dogeza and Akihito thinks he is piyful (he is reeeeaaally submissive to the Kuze family).
Chapter 36:
Akihito's side : there is a 'fake flashback" which is : Tomoyuki's mother was a really beautiful geisha and thought she could survive in this world if she had a baby with a high ranked person/noble. That is in fact what Akihito thinks happened back then. Then Akihito states that his grandpa never went to Shinbanshi!!! (the geisha place where Tomoyuki's mother worked at). So he says that Tomoyuki is either the son of Takamasa himself of Takamasa's father (gosh it is so complicated) and asks Takamasa to reveal him everything for Tomoyuki's sake (yes please do TT).
Then we see Takayuki talking with Hiroyuki and Takayuki says that Tomoyuki's arrogance makes him think of their grand-father (lol so Tomoyuki is is uncle?? XD).
Back again to Akihito, we now know that Tomoyuki is indeed the geisha's son but Akihito says nothing about his father so we still don't really know for sure (ughhhh it's killing me).
Tomoyuki's side : he plans to buy the factory (he really wants to "save" those people).
Chapter 37:
Other than Tomoyuki, Ishizaki's clerks seem so incompetant lol
Then we have Soemon talking with Soichiro and Soichiro learns that Tomoyuki has started to plan his marriage (poor Soichiro ;^;)
Akihito's side : he talks with Tamura, they are at his childhood house (at Kamakura)
Chapter 38 :
Katsurag'is side : he goes to the Katsuragi's mansion to talk with his bro (not so sure anymore fufu) about the fact that he plans to buy that factory. There's also Amamiya. I don't really know why but Tomoyuki needs permission to buy it (well I know Takayuki is the head of a bank but urg I have difficulties to understand all of this orz )
Then we have Tomoyuki talking with Soichiro who is reeeeeaaaally upset about the marriage thing, and asks Tomoyuki to tell him where Kofusa is but he refuses ;_;
Akihito's side : he is reading letters people send him, wishing him a good recovery (lolol) AND THEN!!!!!!!!!!!!!!!!!!!!!!!!!! HE SEES TOMOYUKI ASGFEFQLK you have to go see that on the raws. This scene is freaking beautiful.
Chapter 39 :
Katsuragi's side : a first flashback : he is in a... low-class train (???? how do you say that xD) and I liked this scene because he hates it but still stay because he wants to see his lover asgdolzejfzepf. He goes "outside" of the train tho where there's the train's smoke (how do I described this scene fck just go see the raws I'm sorry XD)
2nd flashback : he talks with Soemon and tells him to take care himself of his son's marriage. also we learn that Tomoyuki succeeded in buying that factory (as expected!!!our man is the best right? xD)
Back to present : Tomoyuki is taking a bath and at the same time is talking with Tamura. Tamura says Akihito took care of Tomoyuki's suitcase himself and then say he thinks Akihito wants Tomoyuki to sleep in the same room and I think Tomoyuki was embarassed because he shuts the door loudly hahaha. I like Tamura xD
Then Akihito and Tomoyuki are talking together and our sweet baby Akihito says he was happy Tomoyuki didn't listen to Soemon about that factory because at that time Tomoyuki did that for HIMSELF (since HE wanted to save those people and all, in other word he didn't obey anyone). Akihito is so sweet TT He says that he wants Tomoyuki to think of himself more instead of doing things for other ;__;
Tomoyuki replies that it is thanks to AKihito that he could do all that, wondering each time what Akihito would have done if he was at his place. (their relationshp I swear-- TT)
Then they kiss (yay!!) and then they tell the other that they smell nice (awww) and Tomoyuki gives him such a beautiful smile aszdzelfzelf (I died).
Akihito says he just wanted them to sleep because Tomoyuki seemed really tired but that he couldn't hold himself anymore once he saw Tomoyuki's smile.
So they start having sex and Akihito asks him to stay the night so that they can properly talk for once (yes boy) and Tomoyuki replies that if Akihito wants him to stay till morning he can just make him not to sleep till morning (hahahahaha you... :') )
So they have sex x3
Then it is morning and Akihito wakes up after Tomoyuki again (lol) and he is rassured seeing that Tomoyuki's suitcase is stil here. Then he asks Tamura to hide Tomoyuki's shoes (lol this kid).
Tomoyuki has a MINI flashback of Akinao telling him he is really smart and all.
Then Akihito and Tomoyuki kiss and Akihito tells Tomoyuki that his father's office was at the end of the corridor on the left and that his mother's room was in the right and that he was born there (HE IS SO CUTE HOW CAN TOMOYUKI RESIST HIM? Well, he doesn't lol).
And the last dialogue are something along those lines :
Tomoyuki : So you want us to talk ?
Akihito : yes
I don't know : There is a lot of thing we need to talk about
The other but since i don't know who said that ↑ : That is true
Akihito : It is complicated there is so much thing I hid from you
Tomoyuki : .... what do you mean???
END.
