He the friend
Just that, right I see thnk u
haejin's mom is his noona (sister)
In Korea it is respectable to call someone older than you Noona. If they were cousin then Haejin wouldn't call Taehyun his friend and in the next couple of chapters it will show Taehyun past about Haejin
but y noona y not tita
Plz guys I didn't understand or maybe I didn't read carefully, wt's tayhun's relationship with this family??
PS: I'm still in 45
