Well this isn't complicated. They where naked together, and she expressed willingness. You don't really need an extensive history with a person to have sex with them. I think something like Tinder might really shock you!
@ other people, it is quite normal to be interested in sex. A healthy desire does not automatically constitute "desperation" for sex. The MCs that act like they totally lack this basic human instinct are indeed annoying. Even more so the ones who feel the need to flee when a women is throwing themselves at them - unless they have a good reason. Very rarely do they have an actual good reason to flee and that is indeed very pathetic as it is very unrealistic. These MCs even act like that's some admirable trait (it isn't). The necessary suspension of disbelief is quite high.
On the other hand it can also be annoying when people act like sex is the only thing there is, and anyone who isn't focused on sex above all else is "beta." Now that this series has gotten that out of the way, it can focus on other things and no one needs to linger on this.
