???????????

The ex scammed him because the ML thought the ex was the guy who comforted him when he was about to kill himself? But it was acc the mc. The reason the dad found out was because I think they had a meeting in school and ex told on the ML and then the dad fought him. The mum knew he was gay because of what he said when he was young about liking a boy. I don’t understand your last question but all of this info is in the chapters

i'm not talking about that scene in particular where the ex tricks him, i'm talking about what happens AFTER that which is unclear?????? how and when did their relationship end and WHY?? if it was because the ex tricked him then how did he even find out??? the only thing we've seen of their breakup is like a 2 panel flashbacks of the ex saying something shitty but we never find out how things get to that point? there's the scene where the ex, who is hanging around shady guys, is on the phone with the ML but there's no context to what the ex is even up to or how long it's been since he started ''scamming'' the ML???

also it seemed like the MC had no idea that the dad found out??? how the hell are we as readers supposed to conclude that OH the dad found out through the school/the ex and then he AUTOMATICALLY concluded that their mother must have left because she found out he was gay with how little context we got?? it's just bad writing

and the last question was about the scene right after the flashbacks happen? the scene before the flashbacks literally just ends with ML running home to confront his mom who's with the MC then out of nowhere we find out he ran away from home after the flashbacks end? tf????????

Nah, let me give u some explanation.
At chapter 26, it said hajin sold his house which is under hajin name. So, his friend ask him to take the house back and cut off with hajin.

The run away happened when Tae Oh's mother came to the house.

So far that's all I can answer. I'll back if I found another answer.
