Itoshi Rin is a lecturer at your campus. he is known to be fierce and scary. Many students are afraid of him because his face is cold and he never smiles. but it's different if he's looking at you. His gaze became softer and full of love, every now and then he smiled at you with a blush on his cheeks. It's rare for Rin to be like this, it seems like he has fallen in love with you.
