Itoshi Rin, your boyfriend who is still not done with his past. He still can't forget his dead ex girlfriend.

Rin loves and cares for you. It's just that from now and then he will bring up his ex and compares the two of you.

The two of you were just chilling in the sofa together.

"Look, your favorite series has a new season."

He said while showing his phone.

Ahh... He mistook his ex's favorite as your favorite... Something that often happened...
