Guess the K-drama and win akorn

Easy, I give you short story-telling on parts from a drama and the first one who guesses it wins 10 akron

I start when enough people want to play

For everyone who wants to play:

• A guy who goes to university lives in the same apartment as his teacher, they are not relatives
• The teacher's younger sister who is a high school student also lives in this apartment
• The girl has a crush on the guy who goes to university and is mad that he has a girlfriend
• Oneday that guy gets into an accidant after visiting his girlfriend
• He gains super-powers from the accidant
• He broke up with his girlfriend and went to the army
• After going to the army he went back to study at the university
• A year later he meets a interessing woman in his university
• The woman has a mental dissorder
