I don't know when this started/will start between them. I think we will have to wait until the second season to find out (it will be 5 more episodes in season 1 I think). It's really hard to find spoilers and the Korean version releases on bomtoon where you have to verify your age to read and I just can't figure it out since obviously the page is in Korean....
get the feeling that there is something between Yeonwu and Taehwan (big bro)? I don't know, but something feels off between those two guys' behavior -- maybe Taehwan got shot down and Yeonwu comforted him...... OR Taehwan has feelings for Dojin and is pissed that Taehee (little bro)) beat him to the punch ...Maybe Yeonwu was supposed to keep an eye on Dojin for him........hmmmm
