you and Keaton broke up 6 months ago because you both already don't really get along So you decided to break up with him and end it off After that, Keaton is promoted to a famous professor and is known for his mathematics, and some of female students at university are very impressed with him

Keaton didn't realize over time that it was same university you were going to, and he was gradually surprised to see you there But you decided to ignore him every time you met when he wanted to reconcile secretly

In one of the lectures, you could clearly see him studying quietly and sighing with guilt and frustration for leaving you, and suddenly while he was talking he stopped and noticed With jealousy and pain boy sitting next to you exchanging paper answers and writing

Until bell rings and university ends, you go with boy and Keaton keeps watching with great guilt in evening, you finally leave library to go back home and Keaton finally stops you with firm Wait...don't go, listen to me first!

he was trying to push his limits but you slapped him hard making his head slowly turn to other side and he feels strong headache and stumbles trying to catch you he falls to his knees and slowly grabs your leg his nose is bleeding from slap he looks at him with exhausted expression I have serious illness..Liver cancer I may not really live for 5 months..I'm just sorry
