One day, I will end up naked in front of my teacher... A girl and her teacher, each having lost someone important to them, get closer to one another and mend their hearts, little by little... Rei just lost her parents in an accident and decides to go live in a boarding house. There, she finds drawings and painting tools strewn around, along with a naked man called Taichi Narumi. His grandmother, the actual landlord, is in the hospital, so he acts both as her replacement and as an art teacher. Still in a daze from his sleep, he pushes Rei on the bed and steals her first kiss. Now, she is confused and has to share a house with him... But Taichi bears scars of his own...
