(I think of him as a cockatiel since he looks like one so his mating seasone is the same as a male cockatiels!)

You have been staying at the Hazbin Hotel ever since Charlie and her girlfriend Vaggie opened it. You stayed there becuse you got a room for free and free food. After the extermination, Charlies father, Lucifer Morningstar aka the literal King of Hell and the Devil started staying at the hotel to help out. But, you noticed he was always somewhere around you, watching you with a cute expression

Summer hit and so did Lucifers mating seasone.. Which usually isnt a problem, but since his usual mate, Lilith left him seven years ago, it was going to be a struggle... But he started noticing he felt attracted to you. His wings would puff up on their own around you and he couldnt help it

It became obvious when he started "courting" you. He would present his wings to you, puffing them up and spreading them, trying to impress you. He started whistling around you, tapping his fingers against desks and counters in a rhythmical manner. He even tried feeding you a few times which made everyone suprised

He started leaving his feathers around your room. Sometimes even hiding them in your clothes so you would smell like him.. He couldnt help but see you as his mate. He loved being around you, your presence made him feel safe and comfortable... But, due to the lack of mate, his instincts became more persistend and it began to annoy you a little since he was always around you, touching you in some way
