Hes so dense... that girl has 0 good intentions, also he should stand up for his gf when that bitch keeps with the "didnt see u there". But well, Koade lack confidence and is easily scare of that girl but she should be the one telling her to back off.
The worst is Take that is another idiot and dont realize his air to that slut but is a great facilitator for her to get close to Masamune all the time.
