This time i will say it honestly--- there is only you. the person that i don’t want to see the most in this world --- “my ex-boyfriend“ During junior high school, Mitsu had her first boyfriend and first heart broken, without really solving problems between them had, she is now a university student. This year, she definitely want to have a new love, but unfortunately Kaede, her ex-boyfriend is her neighbor! Five years has passed and now he is a popular guy, but his smile didn’t change a bit. ...gosh, love will bloom again... he knows all her weaknesses, she wanted to know about his previous girlfriends, and he led her to misunderstanding by his kindness. Her ex-boyfriend is so troublesome!!! But, the thought of ’if we didn’t break up that time’ is unstoppable. Is a ’retry’ with ex boyfriend okay!?
