Down BAD pretenders!

Looking for yaoi with guys who are down BAD for their crush and start act like a bird trying to impress a potential mate: pretending to be cooler/nicer/more competent. Preferably semes, but can be ukes.

Examples:
"Nah I always look like this" but spent hours choosing clothes, fixing hair, etc.
Asks for his friend to lose when combating or gives 150% in training and pretend it was easy to win so he can show off.
Rescues a kitty from a tree and pretends he does it everyday (has never gotten up on a tree before this).
"Of course I know how to pilot a boat" fucking wings it cuz he ain't gonna tell his crush he can't, that'd be lame, etc.

Yk when you get a crush and you you do things you know your crush will think is cool or sweet but if a friend saw they'd think you're soooo lame because uh wtf you doing, you never do that???

I want guys who are liars! Not Bad but they do things just to impress the guy they like and pretend no I didn't, this is destiny, we're written in the stars, I'm just always this nice/cool, I'm not flirting at all! Loser in love behavior (kudos if it works/the crush doesn't notice at first).

Like "oh, somebody asked to trade places, that's why I'm sat next to you" so his crush is thinking he's such a good person who does everyone favors, no, he was the one who asked to trade places and now he is acting nonchalant (This is specifically a scene from Tell Me You Can Hear It)

NOT looking for guys who are actually rude to everybody but is nice for his crush (it's fine if he is cold and pretends he's an extrovert if there's that Loser charm where he has to pretend in front of those who know how he actually is and he looks a bit pathetic for them, not scary) NOR hiding any secrets (like Otaku pretending to not be otaku, that's not adding something, that's detracting something).
Only people inflating themselves to appear more attractive or similar things.
