It really seem like they didn't do anything. Well, I guess it was removed for the sake of making the manga or light novel wholesome but I remember in the original web novel, it was during this time after she revealed herself to him the bath that they did the deed in the bed the first time, and he reminisced in the morning lol. It would've been fine too if they portray or imply as if they did it and hinted to readers as if that's the case, but I guess they really just removed sex all in all. Well, I guess it's wholesome so it's fine too.
