Also, some other notes....
- I'm happy that Jay no longer has to sneak around Taeha anymore. Being caught in between the chairman and the youngest Master and walking the edge of a knife with all those secrets, is not a position anybody wants to catch themselves in! That man was STRESSED! ╥﹏╥ It seems that in addition to trying to save Hae-soo, Taeha is also going to look out for his security guy as well! (๑•ㅂ•)و✧
- The art gallery event for the mother, that the sons were supposed to attend, is about to happen! Taeha is already there at the chairman's request.... Where is Taehee and what is he about to do? ( ̄へ ̄)
- Minshit has been absent for a while, and I'm all for it. (︶︿︶)=凸
- As for the sonogram picture, I don't think Teja is going to use that to manipulate Haesoo into being with him. He found out about a treasured, but sad secret that Hae-soo has had to carry alone, and I feel that eventually, he wants to give her a child. This is no problem, especially since we have seen in previous chapters that he is actually quite fond of children. He wants to give her anything that will make her happy. But Teja is kind of going about things in a weird way. Keep in mind before Hae-soo, he was a virgin and had no relationship experience. His tactics are messy, manipulative, and impulsive. Even Jay picks up on this and tries to give him more experienced advice. Remember he has periodically criticized Taeha's actions and behaviors in pursuit of this relationship- especially when Taeha bought about a dozen wedding rings in anticipation of proposing to Hae-soo (all because she's stressed the seriousness of marriage a few chapters back when she thought he was being too casual about it that subject.) Taeha's efforts, mindset, behavior, and plans of furthering the relationship keeps switching up depending on how he interprets every new thing that occurs between Hae-soo and him. Because of his lack of experience, he's still "childlike".
- Hae-soo is about to enter a world of trouble, now that the older brother (Taehee) has found a new underhanded, yet brilliant tactic to lure her into his grasp.... sending one of his men to the hotel job she works, and propositioning her boss for any extra employees she may have available to work this "emergency position" they need filled. Taehee is going to have her work at that lounge he routinely frequents for drinks and prostitutes! (⊙…⊙ ) Keep in mind, during all of this, Hae-soo has never told Taeha that she was looking for extra work to gain more income to get a new apartment. He has no idea what is about to happen to her if she takes this fake "new job". And Hae-soo is willing to work it, put up with abuse on the job (as she previously has done), and keep it from him, not wanting him to get involved in her messy financial affairs.
I noticed the eye color difference too, from purple to dark purple- but contributed that to darkening with age. (That is actually something that happens in real life.) That the mother seems like a duller version of her former, younger self. Plus, the girl being depicted, looks way too young and childish to be paired with a grown man of 23 years. But that is just my interpretation. ╮( ̄▽ ̄)╭
As for Hae-soo, I don't want to go predicting anything too far into the future, cuz this author has surprised us before! We'll have to sit and wait to see how this plays out.

... I'm realizing that other readers have not picked up on the flashback story of the chairman's wife and him! People are thinking that the presence of this young teenage girl (who thinks she's being sold off by her family) is is another plot twist that is interfering with Taeha and Hae-soo, when in fact, the author has been weaving a new backstory in between the current storyline.
I'm not going to lie, I got confused at first with that teenage girl, but I saw that she had a striking resemblance to the boys' mother. That's when I realized the author started telling her side of the story and how she got involved with the chairman (Taeha +Taehee 's father). The author started telling the story of how her father wanted to use her to solidify connections with the more powerful Beom family by marrying both families offspring together. (They show the young version of the chairman sitting at the table with her.)
In my opinion, the author could have done a better job of weaving their juvenile backstory into the current storyline in a way that readers can pick up on easiler. But his transitions often require rereading chapters or segments two or three times to catch the switch. The striking resemblance of the young girl to the current mother, is the only thing that tipped me off that this was the mother's backstory.
