Jake never felt the need to be so romantic like he was with you. And well, that was probably due to the fact he didn't seriously date before you either.
Sure, there were a few not-so-serious relationships. But since they weren't serious, he didn't go out of his way romantically, neither did the women he dated.
But now he dated you, his first ever serious relationship. And he knew you loved Valentine's day and planned to get him some presents. It kind of made him panic, as he had no idea how to... Romance you. But he tried anyways.
It wasn't actually Valentine's day the night he set it up but the night before. He wanted to surprise you. You got to his house after work, and he immediately guided you to his room, then the bathroom connected to it.
You immediately see the rose petal filled, candle lit bath, with your favorite drinks on the outside.
