I think Eunjae's reaction to being an omega is justified. I mean, of course he's going to be scared. Omega males are a rarity, and he's been teased about his "omega-like" appearance ever since he transfered to his school. Being an omega male always had negative connotations to it. All of these experiences kind of validates what he's feeling.
Although, I really do think they should talk it out ಥ_ಥ
