Nishidate is a trainee doctor at the University Hospital. His goal is to be a Pediatric surgeon equally as good as Odagaki-sensei (an outstanding neurosurgeon and also his instructor when he was a medical student). They have a romantic relationship.

This is were the plot begins:

Nishidate wants to hide their relationship when they are in the hospital, but there is a problem... Odagaki doesn't want that!. He does his best to show him off and lure him to his side, while Nishidate tries his best to avoid him and keep away the "murder nurses" from finding out. This and more obstacles come in his way. Will he be able to resist and keep their secret?.
