Hisashi Uehara

A popular and good-looking guy, and unsurprisingly has a bunch of fangirls. In fact, he made the school's "Top Three Hottest Guys" for three years in a row. He lives together with Nao because of the whole renting fiasco. He's very aloof and antisocial, and gets straight A's without studying. Because he is very mature looking, he is commonly believed to be older than he looks. In Good Morning Kiss, it is stated that he looks a lot like his mother. Both of his parents died while he was still an elementary school student. He had had a big crush on Yuri for 6 years but was heartbroken when she had married his older brother despite her knowing about his crush on her. He then started to date Nao later in the story. He gets mad or jealous whenever Abe shows up out of nowhere or whenever he or any other boy hangs out with Nao. Continuing to give off the cold shoulder, he's outspoken and slowly lightens up after dating with Nao Yoshikawa. To make him confess that he liked Nao, in Chapter 15, Yuri hid Nao in her room and asked Uehara why he did not want to come home. He admitted that it was because he liked Nao, and that although his original reason for leaving home was because he was heartbroken from his older brother's marriage with Yuri, he has gotten over his crush on her and had wanted to be with Nao. Nao slipped down by accident, and he hears her. He tells her he really meant it after Yuri leaves, and does not get his feelings replied back to until Valentine's Day, when they officially become a couple. He lies about his age to get a job and has a surprisingly large appetite. In the end of the manga, he and Nao move into different apartments because the landlady of their previous apartment had a son who came back from America and had wanted to rent out a room for him and his girlfriend. When they agree, Uehara tells Nao that he wants to live alone because he wants to be more independent but tells her that they will never be apart. This ends up as a rumor that Uehara had proposed to Nao and had spread across the entire town. Uehara clarifies to Nao that he did not propose to her but wants them to still be together. When he and Nao move into their apartments, they learn that they live next door to each other because of the help of the landlady of their previous apartment and Nakatsugawa. (source: Wikipedia)
