Toradora! [とらドラ]

Toradora!'s story begins with the male protagonist Ryūji
Takasu who is frustrated at trying to look his best as he enters his
second year of high school. Despite his gentle personality, his eyes
make him look like an intimidating delinquent, so he feels utterly
hopeless about his chances of getting a girlfriend anytime soon, and
does not have many close friends either. After being greeted by his hungover
mother in the morning, Ryūji goes to school and is happy to find that
he gets to be in the same class with his best friend Yūsaku Kitamura and
a girl he has a crush on, Minori Kushieda. However, it is then that he
unexpectedly knocks into "the school's most dangerous animal of the
highest risk level"—Taiga Aisaka—who just happens to also be in his
class, and is a good friend of Minori.

Taiga has a negative attitude towards others and will not hesitate to
snap at people. After meeting Ryūji, she takes an instant dislike to
him. Taiga comes from a rich family, but she has moved out to live on
her own due to family issues. She is coincidentally living in an
apartment next to Ryūji's. When Ryūji discovers that Taiga has a crush
on Yūsaku, and Taiga finds out about Ryūji's affections towards Minori,
Ryūji suggests that they cooperate to win the objects of their
affections. Taiga exploits the fact that Ryūji will do anything to get
closer to Minori. She makes him her personal servant, getting him to do
all her household chores (cooking and cleaning). Taiga spends a lot of
her time over at his house, so much that she could almost be considered a
member of his family. Since Ryūji spends a lot of time with Taiga, he
has opened up to her world and to a side of her that most people do not
see the two also try to help each other improve the way people view
them. However people they know from school start to become curious about
their strange relationship and rumors begin to spread about them behind
their backs. Ryūji and Taiga start getting along more as things
progress with the relationships between the characters and eventually
confess their true feelings of love towards each other.
