Adrien had an inkling that his cousin Felix may have a crush on Kagami. However, Felix could be very buttoned-up (no pun intended) so Adrien knew he had to be sneaky about this.
"Hey, Felix, what's your type?" Felix stared at him. "I like girls who wear pink, run across rooftops…."
Is he going to keep yammering all day? Felix wondered. He didn't want to answer, but if it meant his favorite cousin would be quiet….
"A strong woman," Felix answered, thinking of how good Kagami was at fencing, speaking her mind, the way she flipped her hair. "Like Ladybug," Adrien answered, growing starry-eyed. No question who his cousin had a crush on. "No, I think she secretly likes Cat, she's just playing hard to get. But I've seen the way she bats her eyes at you." "Yeah, she's amazing really," Adrien babbled, cheeks pink.
"Okay, fine! I have a major crush on Kagami! But how do I ask her out? She may be strong, but she scares me." "You know, she's a superhero and has the Dragon Miraculous. Hey, she's like Mulan!"
"Adrien," Felix sighed, "Has anyone told you need to get out more?" "Maybe? And just think, her Kwami's a little dragon just like Mushu!" "Oh, boy. Do you have Marinette's number? I think I'll ask her for help instead."
When Felix went on his first date, he knew that this girl was worth fighting for, and yes, that was a quote from Mulan.
