It's funny how a lot of people hate the sunbae right now. Don't none of yall now what a toxic love between the sunbae and the red head can do to you, especially if you know each other since middle school... 
It's not easy to 'just' walk away from that. It takes a lot of willpower to cut ties with someone you loved almost your whole life. Those feelings won't just go away.. 
All three of them have problems, those problems are a big part of the reason why they act like that, and no not even the red head is a ass****... 
Both just had to learn to approach the problems in a different way, but all those feelings that both of them kept inside of themselves are finally breaking out, and because those emotions are intense of course the reaction to the break out will be intense... 
Both were afraid to lose each other, that's the reason Both of them kept quiet for so long... 
So stop calling them assh****, 😒

Da**... ????
