a mc who fools around/smiles all the time and is carefree, but knows what he wants and will do anything to get what he wants. and you know its bad when he is serious. male mc romance/bl is fine but no harem
Isaac The MC is sort of a mentally deranged character. While the novel is pretty weird, I liked the MC's carefree attitude a lot. A simple reminder that in some places it becomes a little too edgy.
Lightning Degree. No novel eng translation so far, but you can read the manhwa adaptation though it hasn't gone far into the story yet (or read mtl if your brain cells can handle it)
