Yes he doesn't have a good personality and is kinda crazy. But I think he is suffering a lot... it was 10 years investing in one person after all
unrequited love regardless of the length of time is not the other person's responsibility. they've only been together for a little over a year and the relationship began because of an emotionally manipulative lie....
I'm not saying that Taejoo is to blame for anything. I really think he only hooked up with Youngwoo for emotional support (even though he didn't realize it)
I'm just saying that I don't think it's right to invalidate Youngwoo's pain. But the two breaking up was the right thing to do.
Sorry if this got a little confusing.. english is not my first language ╥﹏╥
I mean.. Youngwoo deserved that, really. ╮(￣▽￣)╭
