Love Shuttle

Doyun is a half-Omega who looks more like an Alpha: tall and muscular, with no sign of going into heat despite being a grown man. He sees no reason to worry, and those around him assume he is an Alpha anyway. When his heat finally begins, it strikes at the worst possible moment. With no one else to turn to, Doyun seeks help from his work rival, Taehan, who is more than capable of assisting him.
