Yamada begins to awaken . . .
Also not to be that guy, but the dotted-line eyebrows really should have been a red flag. Who does that? Even so, imagine having the guts to tell someone's friend that you didn't love them but just wanted to get with them because they seem easily manipulated. The guy deserves a pat on the back and a one way ticket out of this manga. I'd be very glad never to see him again.
However Yamada interfering was cute, as was his gloating afterward.
