Testo della bandella:

Per venirne a capo, questa volta, dovrà aiutare una kohai a guarire dalla «sindrome della pubertà»… Un nuovo mistero ha inizio.

Blurb:
“Today … is yesterday?”
Sakuta may have cured Mai’s Adolescence Syndrome in the nick of time, but now he faces a no-less-harrowing task: convincing her to officially date him. After managing to win that round of verbal fencing, he gets some well-deserved rest … only to wake up “yesterday,” with all his progress reset. This inexplicable phenomenon seems to be caused by Tomoe Koga – the self-righteous yet self-conscious schoolgirl who offered up her own butt to be kicked after mistakenly assaulting Sakuta’s – and the only cure is to … pretend to be her boyfriend?!
