I couldn't find a nickname's feed

I came back after reading Alpha Trauma, because I think I read in the novel that Dohyun said Wooyeon is his first love but I'm confused now, here it seems like Yoonwoo was his first love, or maybe Yoonwoo was just his crush, idk
+I forgot how annoyingly persistent Dohyun was, Alpha Trauma made me soft for him
