Okay. Where to start? Oh yeah. I honestly felt warmth for the English Teacher. He is a solid one who actually put the student first instead of personal gain. We need him in these kind of school life manhwa, he is so rare, precious!
And second, that ex dude is really ticking me off. I read the raws and even tho I dunno what the hell are they talking about, I just despised him; so much despised him no matter how delicate the artist drew him, I just ughh. It's going to be a torture for me in the next, next, and next chapter OTL
