Pretty artwork but tbh I found the characters rather annoying. Kazushi was infatuated with blonde, green eyed Rui from first sight. Rui was still in love with his art teacher who passed. The beginning was a bit disjointed jumping over times that things occurred which was a little annoying. I never felt any reason for love between the MCs. Maybe because too much of Rui was invested in his teacher through most of the story.
