Google translator says the title is Graduation Begins with You, by Yvonne. No need to thank me I barely helped.
ok loll but still, tq
I don't think there's an english version out yet, but I found the chinese one on http://www.dm5.com/manhua-biyeyounikaishi/
If i'm not wrong the company that helps to publish their work is http://www.mrblue.com/webtoon/all
The manhwa original name is 너로부더 졸업 . You can try to search by that name.
Ahh thank you for replying (๑•ㅂ•)√
毕业由你开始 is the chinese name of the manhwa, I dont know the eng name or if It's even available on mangago. It's by 이본느 btw. Desperately need help ಠ~ಠ.
