* Shou is who Utsumi was interested in in the first place
* Shou is clumsy, hard-working, not very sure of herself, was born a preemie, and has a comical, middle-class family
* Shou famously stood Utsumi up to go with a crush from her past
* Shou's crush ultimately screwed her over and she broke-up with him (Utsumi was there to defend Shou when that crush was discovered two-timing her).
* Shou was totally distraught when she attempted to make-up for smashing Utsumi's feelings only to discover he and Yuki (who had up to that point been trying to get Shou and Utsumi together) were on the verge of becoming a couple themselves.
