[Marvel and DC] Merlin, the Flower Mage

I’m Merlin, known as the Magus of Flowers. I bit my tongue while chanting a spell and accidentally fell into another world. My hobby is observing humans. Superheroes in this world, for example, make me want to observe them up close. But “Get out of my Avengers Tower!!!” The American sweetheart came to ask me, exhausted: “Merlin, what did you do to Tony this time?” “I just gave him a birthday present. I guarantee it’s what he wants most deep down.” “Then he shouldn’t be reacting like that. What exactly did you give him? Can you tell us?” I told everyone there, hoping they could give me some advice. But they only looked at me with complicated expressions and said, “I understand why Tony blocked you now... Merlin, you really don’t understand people at all.” ...Well, I am half-incubus. So what exactly did I do wrong? Merlin is still trying to figure out people’s hearts today. I tried outlining the story, but having Merlin fall in love is too difficult, so I gave up. This one will have no romance. Theme:
