Seong Ho Han

Seong Ho is hired as the new P.E. teacher soon after Yeong In makes her appearance. He is in love with her, though it is unrequited as Yeong In doesn't even consider him as a prospective partner due to their class difference. He thinks Ha Ji is amusing to observe. [Spoiler] He eventually marries Yeong In and they have a daughter together, with Seong Ho as a house-husband. [/Spoiler]
