didn't feel genuine. Still kinda felt like the ML is a rebound. Feels no effort on the MCs side. Now, the ML is still agonizing over him. The longing still feels heavier on the ML's side. It was a race of the "price" (virginity) of that cool guy. Now it got ruined. So this is now a normal adult-sex-is-nothing trope, which is uncomfortable, because it is not nothing when you started off with fluff.
