Yuki lives next door to both Suzuna and Eichi in apartment 205. He makes his first appearance towards the end of Vol. 3. His Green eyes give away his half Greek descent, which he uses when he models part-time. He quickly falls for Eichi which creates a bit of a competition between Suzuna and himself, until he realises that it is no longer Eichi he likes but Suzuna. His birthday is April 3rd.
