Hmmm... maybe that Doi girl somehow meet Yamada and likes her instaed of Kase. Yamada is extremely popular with boys, could be an interesting new dynamic.
Not another fucking track girl that is after Kase… She havent even gotten the punishment she deserve from the first time yet…
Author if you really want to destroy the manga more than you already have atleast make the next girl go after Yamada and make Yamada act exactly like Kase did, so Kase can get a taste of her own disgusting medicine…
You need to drink an alcoholic drink with at least the same % as your age... anyway, Yamada missed the oportunity to give her a tickling attack while she was defenceless! Just as a... payback!
Some little old lady who doesn't remember any English is going to see them holding hands and wearing those shirts and think "Those two are such good friends."
