-Let's start off with how he got jealous. Basically, you and Hanako have been in an a somewhat official relationship for a bit now and Tsukasa has been extremely touchy over you recently..
-Now, Hanako didn't say he was jealous but he certainly showed it, being more 'annoying' than he normally is.
-He Hugs you whenever he can, especially if somebody else is around to see that you're his.
-He's EXTREMELY clingy and usually just follows you around wherever, if he can't, he'll send his Haku Joudai to watch.
-A lot more flirty than usual as well and says whatever he can to make you blush. He does it a lot more in public spaces.
-And he's suddenly pinning you up against the wall a lot (I don't know, I just feel like he'd do it) for the most stupid shit. Like, he'll pin you against the wall and be like "Hey, hey, hey, Y/N, hey, walls are made of cement sometimes."
-After you finally figure out what's bothering him, he requests doughnuts and hugs as compensation.
