Don't mind me, just want to post proof of this info.Somehow i've been convinced that they've been hanging out since middle school, but wiki says first year of high school, so it probably wouldn't be weird for them to not visit each other's homes yet.
well, theyre friends during school but given how often she's flirting with other girls idk if she's brought up her sister, after all, idk if ppl know mikorin has a pet catWait, why Mikorin's also surprised? Wasn't he like super tight with Kashima?
