Favorite manga of all time

It's finished, not ongoing.
The story's about a kindhearted and polite guy, who looks really evil and is misunderstood all the time for having ill intentions and being a delinquent. Because of constant coincidences and misunderstandings, he ends up gathering people around him that think he's a real strong boss and respect and like him. It's funny that the misunderstandings are never resolved (the mc is in his own world).
It's simply hilarious.

Wow, the romance (they're still not together after 250 chapters though). The story follows a girl growing in the acting industry, finding herself (she always lived for others) while doing so. She interacts and falls in love with a childhood aquaintance (but she doesn't know they've met before). They support and help each other, allowing each other to grow and fix their personality issues. And, i gotta say this: it's absolutely hilarious.

I think this was my first manga. It's about a tomboyish girl meeting a guy that crossdresses so that his father will let him be an actor at school. She finds out his secret and promises to help him. They grow alongside each other and fall in love. At the beginning, it's the girl that appears boyish and the guy that appears girlish, while it's more opposite at the end. They're both strong leads. I love it.

This manga is about a girl that stumbles into another world and has some adventure there. Although she's weak, her character is also strong. This manga is simply pleasing to the eyes (mostly) and the heart. It's also in my heartwarming romance list for the female mc accepting and loving the kinda demonic male mc.
