Episode 5

Satisfied that she has restored social homeostasis by wielding Yuusuke in the same capacity that Mariko is wielding Tsutomu, Mikako decides to bleach her hair one morning and playfully tease Noriji before racing off to school where she inspires a lot of euphoric analytical concourse. Yuusuke is shocked to find that casually courting Mikako is easier said than done, especially when she is focused on her vendetta with the newly-arrived Mariko whose volition for Tsutomu is his company during a shopping trip. While Mikako prosecutes a a euphoric nocturnal engagement with Risa and P-chan where it is proposed to create a social circle from scratch, Ruriko converses with Hiroaki as she reminisces over her collaborative prologue with Mikako who once attempted a medically dangerous stunt as a child. Mikako gives the matter some serious thought and announces her decision the next morning —- a social circle that makes handmade items to sell at flea markets. The irony here lies in Jiro's inquiry of whether anybody can truly join cornering Mikako into a conundrum where her jealousy is the liability it actually is; fortunately, Mikako wisely demonstrates that her love for her new social circle is ultimately much greater than her hatred for Mariko as she races home past a very relieved Ruriko to get right to work.
