Bro, I watched GuP in 2016 as a little child, and I could never ever imagine that i will become the main translator in my language community and possibly a dubber too
Funny thing is that all the ooarai freshmen the m3lee crew are in a relationship. So this adds salt to the wound for Alisa. Basically they are patronizing her while making fun of her.
You know, it's possible that Takashi left her for this reason, maybe Arisa was a bit of a stalker and a bit possessive, he was probably checking her cell phone or spying on her location to find out where she was! Arisa is kind of intense! xD
