Turns out the one spreading the rumors was Hashimoto, who did so at the behest of Sakayanagi. Shortly thereafter, Sakayanagi appears before Class C and she informs them she has evidence regarding the rumors about Ichinose.
I spent six months rebuking myself.
ظللت 6 أشهر أنقد على نفسي
Ein halbes Jahr lang
versank ich in Schuldgefühlen …
Pasé medio año culpándome
Pasé medio año culpándome
Pendant six mois,
je suis restée cloîtrée dans ma chambre,
e per sei mesi
Passei seis meses me repreendendo.
Полгода… занималась самобичеванием.
