Romance Mangas be the best, all the way <3 Even as a man I just find them so adorable.

More suggestions from me:
Watashi ni xx Shinasai!:
In class, she's a sort of zoned-out girl, and he's the year one class' most perfect, good-looking guy. But the two of them have a secret, and their extraordinary "love experience" will start now! Himuro Yukina, known as the "Absolute Zero Snow-woman" is a cold and observant girl. In addition, she is actually a popular cell phone novelist who goes by the name of Yupina. Sadly, with no other human contact than her cousin, Yukina is unable to express more romance in her novels. Kitami Shigure, your so-called "typical bishounen", who is really a womanizer, has fallen into Yukina's trap when she blackmails him, and Shigure ends up doing Yukina's ''missions of love''. As this continue, will these ''missions'' be a opportunity for them to fall in love?

Last Game:
He's rich, he's smart, girls gather around him all the time, and he has always gotten first place on his exams... well, until Kujou transferred in his primary school class. She was quiet, plain, and poor, yet not once has she failed at beating Yanagi, both in academics and sports! Yanagi has made it his life goal to defeat this girl Kujou, and ten years later, as they enter high school, he just might finally win! This is the story of their last game.

Hiyokoi:
Hiyori Nishiyama is a 15-years-old girl who is extremely shy and short. After being hospitalized for a year, due to a car accident, she starts going to high school as a freshman, along with her best friend Ritsuka. In her class there is a boy who is very tall and seems to have a lot of friends. His name is Yuushin Hirose and becomes Hiyori's friend (even if at the beginning Hiyori is not very happy with his habits). After an accident where her panties were shown to the class, she starts making friends and falls in love with Yuushin, but due to her shyness, she does not know how to confess to him.

Nisekoi (KOMI Naoshi):
Their families are currently at war because of business rivalry: the boy's family are yakuza while the girl's family are gangsters. The leaders of both groups would like to get along, because if the war is not stopped, there will surely be many casualties. The problem is that their underlings won't listen to them, so they decided on something that will make them cooperate. They want Ichijou and Kirisaki to become lovers, so that their families will come to an understanding with each other. Will the two of them become official lovers and make their families get along? Or will their families continue to fight and create many troubles along with it?
