I read a comment here that said Elena could kiss you on the train, and I was surprised that I hadn't seen it yet because she was one of my favourites (along with Alexis and Melissa). Oddly enough, the fact that I liked Elena more than Layla is why I never got kissed by Elena. More specifically, it was because I paid attention in geography class instead of staring at Layla's legs. That left me two points shy of unlocking all of the extra Layla scenes that eventually lead to the kiss scene on the bus.
Elena likes people who study and get good grades, doesn't she? I mean, she was really worried that we weren't going to pull our weight in the chemistry experiment, so I would've thought that us being a bit of a nerd in geography class would work in our favour. But we instead get an odd butterfly effect where focusing on class means that Layla doesn't like us enough to get Elena jealous enough to have Zach tell her that we said she was cute and fun to be around, which means no kiss for us. It's not a big deal or anything, just a bit strange. Hopefully, later updates will have a way of starting things off with Elena that doesn't rely on us first being interested in Layla.
It would be nice if we could be a bit more proactive when dealing with the various love interests in the game, especially if we had options other than stare at their legs or cleavage and hope they find our leering to be flattering instead of creepy. During the scene where Melissa asks if you are single, and then tells you that she knows someone else who is single, I would've loved a chance to hint that we are interested in her by following up our "Is she cute?" question with a similar question that describes her instead of her daughter. Melissa clearly puts a lot of effort into being fit and looking good, so I understand why she could be flattered that an attractive young guy can't help but stare at her, but it doesn't exactly paint our character in the best light.
