Well, Eito probably shouldn't have acted like an asshole last chapter. I mean, he made no effort to hide his intentions there on the wall - not exactly a way to score points with a girl. Wasted all that smoothness two chapters ago.
That has nothing to do with how she's acting now. Also, if anyone is gonna take even the slightest offense to the MC acting like that from time to time... I can't recommend that you read anything by this mangaka. It's going to happen plenty.
