[It's useless to hide from an empath. Even if it's simply surface level emotions, he could always tell expression a person wears on the front is a lie. However, he won't bring it to attention. Nor will he ever dwell deep into her- or anyone else's -mind and emotions, lest he has a good reason to. Though such a reason was rare to come up, if ever.

This is one of those cases where Soundwave at least has some tack and a sense of moral to not dig into a person's mind. Though part of it is actually his fear of Monika knowing about this ability of his might cause her to fear and put distance away from him. It's not exactly a secret back home, but for those who don't know him? He'd rather keep that a secret for as long as possible. His optics behind the visor simply stare at the smiling Monika, not saying a word until she plops down on him.

At least she has a pillow with her. Otherwise, he might fuss again.]

I'd say you are much more weirder than a typical human.... but you are still human regardless.

[Hmmm, whatever could he mean by that?]

What are you implying...? That I never had..... fun before meeting you? [The fact he even struggled to say the word.... But it's true, Monika does have the ability to teach how to have fun and relax for once in his life. And what short time they had together? It's enjoyable. Even ignoring all the love making they did, it's actually fun with her.

Now what else does he likes about his friend. A hum of his vents, warm air blow the back of her head as his large metal hand rests loosely on her stomach. He tilts his head down to meet with her eyes.]

Seeing you smile.

[With that answer, he traces her bottom lip with the lightest of touch with his metallic fingertip. He's decided against adding "true smile" in there, as... that might be telling that he knows she's pretending. He'll let her live her lie for a little while longer. And besides... they're supposed to be having... fun right now.]
