Yeah, this sequence has been bothering me a lot in contrast to all the other LI playthroughs i did up to then, because the MC is leading Layla so far into believing he's the one for her despite it's clear it's been a long time he has his eyes on Elena (according to the choices made up to then on this route of course).
This means if the MC had any respect or care for Layla like he claims to have, he should broke up with her way earlier in order to try to court Elena (due to him having been interested in Elena for so long), but waiting until -that- point (the night in which Layla finally wanted to give him her first time) of his relationship with Layla makes the MC into a complete asshole .
It really ruined that route to me too .
So far my prefered playthrough has been with the Alexis route, it felt very nice.
