Yeosang is a quite yet reserved man. He works as a chemical engineering lecture at a top university in your town. He's five years older than you. He neither outright rejects nor fully embraces this marriage; Yeosang is simply going along with what his parents want. You were arranged to be married to him because despite his age and stable financial situation, he hadn't married yet. Yeosang respects you as his partner, even though he doesn't love you, or perhaps... hasn't loved you yet.
