(from wiki)

Yuki is depicted as an attractive, reserved, and accomplished young man with many admirers, but who finds being friendly quite difficult. As a young man possessed by the Rat, the animal that according to Zodiac legend was first to arrive at the initial Zodiac banquet, Yuki is talented at anything he tries (except cooking and cleaning). However, when Yuki was young, Akito Sohma kept him isolated from the rest of the family and convinced him no one liked or needed him;   because of this emotional abuse, Yuki has low self-esteem and feels isolated.[He has a fan club headed by Matoko Minagawa that tries to "protect" him from other admirers, with the result that Yuki is further isolated.  Yuki, however, wishes that he could be with people as friends, rather than be admired from afar, and envies both Kyo Sohma's and Kakeru Manabe's easy ways with others.  He is touched when, faced with the prospect of having her memory of the Sohma family secret erased, Tohru asks that he remain her friend,  which no one had asked him before.

With Tohru's help Yuki is gradually able to "open the lid" on his feelings, and the summer after she begins living in Shigure's house, Yuki admits to himself that he loves her. 

Yuki's worst enemy would be Kyo Sohma, the cat of the zodiac. Hatsuharu Sohma felt animosity towards Yuki during part of their childhood because of the story often told to Haru about the rat taking advantage of the stupid cow; this made Haru develop an inferiority complex towards his older cousin. However, after actually meeting Yuki face-to-face, Haru was able to see Yuki's extreme kindness and developed a deep admiration for him.

Yuki also feels a close connection with his cousin Kisa Sohma, as Kisa was teased because the children in her class thought she was different from others. Until Tohru Honda touched her heart, she didn't go to school and she couldn't speak, much like Yuki back when he was younger. Likewise Yuki, despite his popularity, rarely interacted with anyone on a personal level and was extremely private and introverted. Until he met Tohru, Yuki was afraid of becoming close to anyone because of an incident during his childhood when his secret was discovered by his friends during a game of tag, when Akito ordered Hatori Sohma to erase the children's memories, thus leaving Yuki alone and without friends. After meeting Tohru, Yuki started warming up to other people and becomes much more social, as well as accepting who he really is. He even becomes close friends with the other members of the student council during his time as president.

Yuki also appears to have respiratory problems, due to his weak bronchial tubes, and gets regular checkups from Hatori to monitor his condition. In his childhood these asthma attacks were apparently frequent, though they appear to be less so in the present.

Later it is revealed that his feelings of love are simply love for a "mother figure" (of which Tohru becomes for him).
