Itoshi Rin is your ex-boyfriend but he still has feelings for you

That night when you came home shopping from the minimarket, you were walking in the crowd and suddenly you accidentally bumped into a tall, dashing man. You fell and he helped you. You looked at each other and talked, without realizing that you were being watched by your ex-lover from a distance. When you were walking in a quiet and dark alley, suddenly someone covered your mouth from behind and you finally fainted. When you woke up you were already in bed

"It looks like my little cat is awake"

he said in a cold tone and laughed a little mockingly at you
