#this will probably prompt klavier to stop the flirting and confess his feelings immediately

[demonadelem]

I don't think Apollo would be unaware of Klavier's flirtations.

He would pretend to be unaware but he's known since "first time I felt this way about a man." Pining unaware of each other's affections is NaruMitsu's thing.

Apollo thinks Klavier just wants to sleep with him but he's not "that kind of guy," and "Klavier isn't really in love with him". Apollo catches every double-entandre and complimentary remark when he starts hanging out with Klavier with Trucy but for some reason he doesn't want to give Klavier a solid rejection. Trucy constantly teases Apollo about them but it's true, he secretly enjoys it. Maybe Klavier isn't such a bad guy.

During turnabout serenade, Daryan recognizes Apollo as Klavier's latest project and gives him fair warning, confirming his worst suspicions. Klavier is a bit of a player, a serial flirter as much as he is a serial dater, jumping from girlfriend to girlfriend to boyfriend to girlfriend. As much Klavier rattles on about love, when he is asked commit to a relationship, he can't. Daryan speaks with an air of first hand experience.

But Klavier is earnestly in love with Apollo.

This entire time he's been afraid of commitment out of fear of making them the target of Kristoph's wrath. Now Kristoph is in prison, he's not scared anymore. Apollo is the first person Klavier has ever seen stand up to his brother. The rockstar really thinks Apollo is the most amazing person he's ever.

Klavier doesn't care what other people think about him being friends with a defense attorney. He'll help Apollo with cases he isn't prosecuting and befriend Trucy, Athena and any other friends Apollo has to get close to him and die inside every time Apollo brushes him aside. Klavier even stopped going on dates, he doesn't want anybody else. Not that Apollo knows any of this.

This is their stalemate, this is how they would pine.
