wait i dont understand the last story. so the mc got married but somehow couldnt forget abt the nis-san and slept with another guy while thinking abt him and then?

from my understanding the nisan was waiting for him.... then he went to him at the end.
He thought the flower meaning was "only thinking of you" and "looking forward to the day we meet." when he finds out at the end that it could also mean New love/Reunion. he realizes and goes to him.
Hope that helps :)

Sorry that I'm late to this party, but for future readers I wanted to straighten out a few things.
First, she wasn't a wife. She seemed like a girlfriend pressing for marriage. I say that because the guy says, "This happened several times" as if she was one in a long line of girlfriends that all broke up with him because he didn't really love them, he loved the Oniisan. The MC is the one who says, " I'm in love with someone else", not the girlfriend. When the girlfriend leaves, it finally dawns on him that he has been in love with the Oniisan all this time and he goes to drown his sorrow and confusion at the bar. While there, he smells a scent that reminds him of the Oniisan. He hooks up with the person wearing the fragrance for two reasons. One, he wants to know if he really is gay and two, he is attracted by the scent. He doesn't even know if the Oniisan is still at the house where they met. So, it wasn't like he could just take off to the Oniisan's side when he realized his feelings. He was drunk, emotionally strained and sexually confused and frustrated. He "struck" at whomever was closest. Once he gathered himself, he went to visit the Oniisan. Luckily, the Oniisan was still at the house waiting for him to return. We see this play out in two or three pages, but the passage of time seems to be more than just a day or two.
Thanks for allowing me the opportunity to give my "two cents" in this conversation. I appreciate it.

can we have a manga focusing on yuu as well? he'd be the perfect girly-looking seme. i kinda want him and towa's eldest brother together heh

Ah you dont know its out already and Yuu will get bigger and many like his brother if you do remember him though
the name of the manga is Aikawa no Konton Taru Mirai
here the picture of Hisa-nii and Yuu

and kimiko is involved somehow
oh and we just got the news that the team who picked up the project is dropping it, cause some people didnt respect their work and put chapters without credits, and now all fans are screwed

>w< here all grown up

Ahh did they have to make him that tall I feel sad especially about the age difference already... not that I don't like it (it just feels weird especially because it is Yuu and Hisa-nii)( ̄▽ ̄||)
the art is really pretty and hot! i want to read more mangas by this mangaka :3
