I like the art style in this chapter.
Also I wish this was a joke but in reality this is actually the case. Red heads, Yanderes, KMS, Hololive, you name it, we got it in PVP Exercises.
It would really be insensitive of Sumi to charge him after dragging him out to the beach against what he originally planned. After all, she's firm about helping Chizuru.
I can't sense character progression to tell whether she's being honest or not.
Also isn't being an idol and going on a rendezvous with a guy at night a risky move for her career?
