This shows that Yahwi's immature as fuck... he's old now to think, you mean that shitty logic was in his mind the whole time? he needs to grow up. That kind of idealism in not working and its not worth pursuing. He should've done something else instead.
If this backstory was shown way back then yawhi will realize that shitty grandpa was wrong and treat Jooin better. But I prefer a different back story, this backstory is cliche, bland, boring and not interesting. Author-nim could've gone to a better route.
Jooin : " I thought it wouldn't impact you no matter what I did"
What you did ? WHAT DID YOU EVEN DO JOOIN ? YOU WERE JUST DRAGGED AROUND BY HIM EVEN WHEN YOU SAID NO ! You did absolutely N.O.T.H.I.N.G
And let's talk about Yahwi. Bitch ! You trusted your mom and she ... Died ? So you decided to not trust or get attached to anyone so that wouldn't abandon you ? Is that you back story ? The disappointment ... And I was expecting anything (︶︿︶)=凸
