I'm crine

I was thinking the same thing, I'm gonna go back and see if there is any change in character. My prediction is the younger one is moving too quickly and the other one is takin his time. I will report back

So there is a switch, I think... my theory goes like this. The older twin was the one that brought ml home the first night i think and they ended up doing it. I wanna say the older twin also shows up in these scenes: when the ml gets wasted in his room and then older twin come over to clean up and then they end up doing it, older twin helps him buy the new clothes and massages his feet. He's also the one who dropped off younger twin at school ND is the dude in the hodie.
The younger twin is the one that did the stuff in the class room and did it with the ml the second time, he's also the one that does a lot of pda. He's also the one sleeping over in the beginning. I'm also not sure but I think the older brother is using the apt next door. And the younger one is the onl constantly crashing at the ml place.
For the cover art there is two collars, the blue is younger twin, and the red is for the older twin.

I think the younger brother definitely likes the ml but I think the older brother is too and he's gonna put his foot down bc the situation is becoming too messy
