I came here after seeing raving reviews on TT about how much of a green flag ML is, and ho...

Whats not green about him? The fact they they have rough seggs?? Because ml treats mc well, he does after care and cares about mc when they’re doing it. But everyone’s definition of green flag is different I guess! To me he’s pretty green, it’s just that they have a lot a lot of seggs & that he looks like every fuckboy ever which maybe seem like he isn’t green def not a traditional green man LOL but still green in my eyes. Also his intentions are always pure/good!

Their first time was anything, but green. It's one thing, that MC is shy and hesitant, but it's a whole another story, when ML basically just pushes him into the bed, regardless of what MC says and does. A bit of rough play is perfectly fine, when you two know eachother well, and can tell, that the other person says "wait" or "stop", or pulls away without actually wanting to stop. But as a first time, as nothing but strangers? Definitely not.
Besides, their relationship progresses way too quick, with little substance to actually justify them professing love, exchanging rings, wanting to move together and wanting to get married. I get that this is more porn than plot, but at least hint in some meaningfull way about time passing, so it won't seem like they met 3 times in 3 months to have sex, and then decided that it's forever love.
