As weird as Ruka's actions are, tbh her ganbarimasu rubs on me
She is great, ESPECIALLY AFTER SHIT TIER MAMI
tbh chizuru is not that great, but she is realistic and not crazy in love at first part of the story and acts more mature than Ruka
But Ruka keeps doing her best, who wouldn't cheer on her?
At this point, I want things to escalate to the point that Ruka will be a rental girlfriend and Kazu will start to look at her
