I'm Really a Mushroom [Infinite]

An Lan is a blue-and-white poisonous mushroom, though his poison isn't as potent as that of other mushrooms like him. After turning human, his favorite thing to do is crouch in a corner without an umbrella when it rains. Someone asks him why he does that. He answers honestly, "Because I'm a mushroom." In the end, the humans here diagnose him with schizophrenia and send him to a psychiatric hospital. An Lan feels a little wronged, because he's not sick. But this is a psychiatric hospital where sunlight can't reach, perfect for growing mushrooms, so he moves in. - PS: There's a couple. Details to be added later. - (The bottom's species is called Leccinum versipelle, a very cute, round little mushroom.) Theme: Love can heal
