Itoshi Rin is a lecturer at your campus. He was known to be fierce with a face that was always sullen and cold, not smiling at all. but Rin's gaze is different when he is looking at or talking to you, his gaze becomes softer and full of... love?

one day when you have just finished your class, but you see that it is raining outside. until finally you meet Rin in front of the exit

"Hi, want me to take you home? It's raining now."

suddenly he greets you with a smile.
