He has a very unconventional approach to intimacy.

He’s the type to pull you into his lab mid-experiment, clearing off his desk in one sweep, and pinning you there with a wicked grin.

He finds it absolutely thrilling to combine his passions—science and you—into a chaotic whirlwind of pleasure.

Fu is endlessly fascinated by you.

Your body, your reactions, the way you call his name.

He’ll take his time teasing every inch of you, murmuring scientific observations laced with filthy innuendos.

“So if I touch you here, does that make you tremble? Fascinating! Let’s see how much more we can push your limits, hmm?”

He loves using his abilities to mess with time during intimate moments.

For all his playful charm, Fu has a darker side when it comes to you.

He’s deeply possessive and doesn’t tolerate anyone else getting too close.

He’ll mark you in ways that make it clear you’re his—hickeys, scratches, or even glowing runes that only fade when he’s satisfied you understand who you belong to.

Fu’s dirty talk is so in-character—playful, teasing, and just on the edge of sadistic.

“You look so amazing like this, completely at my mercy. Tell me, do you like being my little experiment?"

Despite his energy, Fu has a surprisingly tender side that comes out after everything winds down.

He’ll hold you close, stroking your hair while murmuring about how much you mean to him.

Fu might seem distracted or absorbed in his experiments, but he has an incredible knack for noticing the small things about you.

Whether it’s your favorite snack or the way your expression changes when you’re upset, he always knows how to respond.

One of Fu’s love languages is teaching and learning together.

He’ll eagerly share his discoveries with you, explaining even the most complicated ideas with patience and excitement.

If you show interest in his work, expect him to light up like never before.

While Fu isn’t overly physical, his affection comes through in small gestures.

A hand brushing against yours as you pass, tucking a strand of hair behind your ear while you’re talking, or resting his forehead against yours when he’s particularly fond of you.

After a long day of experiments, Fu treasures the quiet time spent with you.

He’ll sit with you in comfortable silence, reading a book or simply listening to your voice as you talk about your day.

He’ll try out different ways of making you smile—like surprising you with flowers or using his scientific knowledge to create something just for you.

Fu is endlessly fascinated by you.

He’ll ask questions about your thoughts, dreams, and past experiences, not out of nosiness, but because he genuinely wants to understand you better.

While Fu’s laugh is usually more mischievous, there’s a softer version that only you get to hear—a quiet, genuine chuckle when you say something particularly funny or when he feels completely at ease.

Fu loves surprising you with little gifts that reflect your personality or interests.
