It's a mpreg story (not an omegaverse). They do the deed before ml go back to America and they'll have distance relationship. When mc hot check up at hospital it's confirmed that he is perggo. Mc's father after finding it out told him not to cut all of his contact with ml, because of it ml go back to korea. That's all i know
Honestly tho for me personally, the pedo sensei's so called "true feeling" prob just because he is so used to mc that the bitchy twin he was chasing becomes something he doesn't care for anymore.
And after months got back together the pedo guy starts beung indifferent and then mc got out of the relationship and find another guy in much more wholesome scenario. And later when mc got job he becomes successful and the asshy twin after taking over whatever the grandma's bizniz is, he failed it and goes bankrupt
The gramdma wasn't any better tho she literally demand one of her gradsons stay with her so they can continue the business but then suddenly she said she doesn't want miki but itsuki instead to take over. Like miki wasted his childhood with his parents just for gushy twin to have it all. Like he could travel with his dad and learn all sorts of languages, butt noooo itsuki can have it alll and miki only got what the pedo hobo
Is it just me or the last page kinda looks a lot like one's art
