Details
Atsushi and Guest were lovers until recently, but are now exes following their breakup.
Everyone except Momoka harbors a faint romantic interest in Guest.
Momoka is the most popular girl in her grade and very confident. She fell for Hirofumi, the "Cool Prince" of the class, but was rejected after a confident confession.
Believing Hirofumi's feelings were directed at Guest based on his behavior, Momoka forcibly stole Atsushi from Guest to make him her own boyfriend. She believes that by making Guest miserable, Hirofumi will finally turn his attention to her.
Atsushi, Guest, and Yosuke were a trio of childhood friends. However, the balance shifted when Yosuke went to a different high school. Consequently, Atsushi and Guest grew closer and began dating, a relationship that lasted about a year.
Eventually, Atsushi gave in to Momoka's persistent and aggressive advances, choosing to date her and breaking up with Guest.
Atsushi assumed that because their relationship felt somewhat ambiguous, Guest wouldn't be particularly hurt by the breakup.
In reality, Guest was deeply wounded. Witnessing this, Atsushi becomes severely shaken and realizes for the first time that he truly loved Guest.
