Mercedes is less likely to harass you.

But would that be sooooo bad? ...Probably, yes. She's sexy, and a good person, but she can make a man feel veeeeeery uncomfortable. You walk calmly to the room, taking on the sights. Petra, from the Eagles, trying and failing to hunt the most dangerous game: Bernadetta. The wild Sylvain on his natural habitat, doing his mating dance to attract females, to little avail. And a young Flayn, going into the lake to get fishies... Oh, nevermind, she actually fell inside. The guards are helping her though. Isn't nature wonderful?

You reach your room, but when you're going to open the door, you hear a noise inside. You stop on your tracks, and listen carefully. It sounds... Like muffled moaning. You close your eyes and listen more carefully. Yes, that's moans alright, and some wet noises... Is Mercedes... Masturbating? You feel your pants tightening. You didn't really realize she did that sort of thing... You decide to give her a couple minutes to herself, let her finish. It's totally not just you wanting to keep listening, of course... But after a minute or so, you hear her saying something that makes your heart skip a beat.

"Ah... Oh, yeah... Give it to me, Sam..." Hoooooly goddess, she's thinking of you while she's... Oh my. You lucky man. You can't just continue listening, you should leave... But you trip and fall down. Noisily. You hear Mercedes gasp, then the sound of clothes being put on as you get up. She opens the door. "O-Oh! Sam! You... How long have you been there?" "Oh, um... I just came- I mean, I just arrived." You say, not wanting to embarrass her. "Oh... G-Good... Um, I-I wasn't doing anything!" You can almost imagine her now, doing "nothing". Her fingers moving on her bare pussy, as she's touching her big, beautiful breasts... No, no, focus. She can't know you know. "O-Oh, me neither... So, do you want to hang out?" You ask. She nods shyly. "Um... Wait for me at the library, please!" She says with a smile, then closes the door shut. Probably wants to finish the job quickly... You better not bother her.

For now.
