SPOILER—
As everyone else has said, it's uncomfortable that Dylan and Keith treated Lucas that way + their relationship made no real sense. I've read tons of manga with similar plots, but this one didn't carry it out properly and it was overall weakly put together. It made my chest uncomfortable the entire time because it (Keith and Dylan's situation) felt really unresolved. Although I do think some of the plot was potentially lost in the translation.
I rather he end up with the brother than the current ML.
but i think seme's brother is also bottom and he likes the bartender :(
Yeah he's got major bottom vibes
True (╯︵╰,).
