If I'm not mistaken, the're from Yashiro's old crush (the doctor) that Yashiro stole back in their school days. Doumeki knows about this crush and found the contacts case in a drawn once he was in Yashiro's place. He stole it out of jealousy. I don't remember if Yashiro noticed they were missing back then, but now he knows Doumeki took it. Not sure why he still keeps it.
Why is the contacts case shown like that as if they’re going to be a big deal plot point lol like that is seriously not a big deal at ALL
