Sadism Overflowing From Beneath His Smock

Asahi is a doctor in training who reunites at a hospital with Yamato, her classmate from middle school. Yamato used to be nice, and they promised that they\\\'d become doctors, but for some reason he\\\'s transformed into an unbelievably cold-hearted heart surgeon... \\\"I\\\'ll train you,\\\" he says, and starts to teach her medicine know-how, but then adds: \\\"I need to relieve some stress. You can pay me with your body,\\\" then suddenly gives her a long deep kiss just a like a lover would! What is Yamato planning!?
