Otomen he's adorable ~
The guy isn't the jealous type, but he sure blushes a lot 🙂
Beauty Pop Later in the manga, the guy gets jealous very easily because he's hot-headed

Love Celeb possibly?

Shinobi Life. Soooo cute.

Magico (IWAMOTO Naoki) -- The male lead blushes more frequently than the female and has nosebleeds to boot. Looking for a similar male lead led me to this forum thread, lol. It's a pretty new manga. Although its obvious that he likes her, he's gentlemanly about it. A pretty awkward, endearing and dedicated guy.

Suki desu Suzuki-kun!!
The guy blushes excessively.
