Maybe more of a 2.5? It wasn't good, but like it wasn't that bad.
This is about an idol who's kink is getting touched on the train, but one day a guy interrupts him because he thinks he's being molested. Annoyed the idol makes the guy take the position of the dude he scared off. Then it becomes about their developing relationship.
I have the same thing to say as most other things published by Mobile Media Research, it's mostly sex and lacks substance basically. Like you can tell there's something deeper happening, but the sex overshadows everything else so there isn't enough time to get to know the characters fully. It's a pretty fast smutty read though and it's not awful so I didn't mind it. It just could've been better.
