At this point Sunyool should just give up on Jisuh. The author is really pushing this narrative of Jisuh disliking Sunyool a lot, to the point where is kinda makes him look like a prick.
I hope Sunyool tells Jisuh the truth about Heejae because it looks like Jisuh is going to jump into some type of dependency relationship with him.
Can we please summon a good man for Sunyool, Author-nim?

You can buy it legitimately up to volume 7 on Kodansha. https://kodanshacomics.com/series/black-panther-sweet-16/
....her backstory is sad but I still think she's trapping JH for money. I could be wrong tho.
