Lol, calling it gyaru girl is preggo with Maa-kun's baby and got a 9-month belly in the half hour before cutting back to Amano's tourney.
I will not accept any other answer even though next week it will be something different.
If he is there for the gyaru, when she already has a childhood friend who would pretty much kill to be in his place, then Amano should just finish with him, and show her pantsu to someone more reliable.
