Somaya and Komatsu are getting along together more than she is with Kotou, almost made a cliché transference love there.
Somaya is jealous, think it was established a few times, he had a rough childhood now is getting back by abusing anything around, cliché bully.
Kotou is now without a necktie, guess his feelings will overcome him after seeing them getting along so high in morale...
Thanks for the scanlation!
