Hear me out
I think the author is giving us these flashbacks to justify and explain why joowon treated haesoo the way he did. In the beginning when the author was explaining their relationship they made joowon look like a completely emotionless bastard that only wanted to keep haesoo to himself. As you can see now he wasn't treated that good by his parents even as a child so that might have been what caused his possessiveness towards haesoo. Also in some of the previous chapters you can tell that he had genuine feeling for Haesoo and even wanted to propose.
Haesoo at first had only stayed with Taku to get Joowon and himself to lose him feeling for his parents sake. I mean i think we could all tell that at some point Haesoo was in love with Joowon. My point being we are still not completely sure of his feelings towards Taku though is they are just to help him forget about Joowon or if they are real.
This is just what i kinda realized as i was reading this chapter.
Of course this is just a prediction or whatever idk what happens i haven' t even read the raws so, don't come for me.

yes it is a common in a plot to create a flashback or explanation as a form of sympathy or closure out of one person after they went thru something bad. This called Falling action where the plot is trying to tidy it loose ends. From this it's clear that Joowon is the main character, soon it will reach to conclusions.
I feel like Haesoo is gonna end up with Joowon because if he doesn't then the whole plot wont make sense. I mean Taku gives me weird vibe, because he didn't really like his last boyfriend. He also seems so emotionless. I mean on the chapter where Joowon wanted to give Haesoo the ring i felt really bad for him, because he had strong feeling towards Haesoo. I mean the anxiety i get from this manhwa is just smt else.
I kinda agree with you,cause it literally says in the summary "Taekyung came in between the two of them", so Haesoo and Joowon are technically the main "couple" and in most stories, they always end up together.
But i may be wrong this time cause Haesoo is not exactly in love with Joowon currently(i think) and he seems to be heading more towards Taku's direction right now.
But you never know, the story could do a 180 at any point.
Well let's just wait till the end, and find out.
This will looong( ̄∇ ̄")
Ok. So Dongha originally was the type of person who didn't want to show his feeling or have feelings for people. They made him feel weak he thought it was stupid. I mean i still like him. He finally fell in love with someone fro real. HE doesn't know how to express feelings, so gets obsessive.
I mean maybe as time goes on for the two together he will have a character development. ╮( ̄▽ ̄)╭
i loved ha woons super adorable development.
