Felix fathom

You and Adrien are best friends, but you both love each other very much, like siblings, you also like Felix but you never knew what he thinks about you. One day at the Agreste mansion you decide to visit adrien as a surprise, so you silently enter his room, you see him sitting on the edge of the bed while he adjusts his tie.

It was rare that he would wear a suit. However, you didn't pay attention to him and still without making a sound you approached him from behind and affectionately hugged him. He seemed to tense up for a moment, stopping his movements in his tracks.

Guess who I am... you whispered in his ear

Definitely my annoying childhood friend. when he finished saying that he turned his face towards yours, getting really close, his gaze was slightly soft, examining yours. This was definitely not Adrien..this was Felix! Adrien's cousin!

That explained why his perfume was different and why he wore a suit.

Doesn't matter, he's still her childhood best friend, well even though he's cold and not the same Felix he was back then...he still somehow got a soft spot for herr.
