Must be bcs despite having a child with MC, he's the only one who still treats MC as his master rather than a spouse, unlike the two who claims him to be theirs and actually acts like his husband. It feels like a line between them was still there so he still feels like a 2nd lead.
I hate that he does, prolly just my personal taste but it's like, he's literally one of MC's husbands yet he's forcing himself back to the pinning unrequited love guy mode like damn. If he was a bit assertive, he'd be my fav for sure.
It's surprising that Sion literally feels like a 2nd male lead despite the webtoon being about 4p couple/family/whatever the fuck you call it. Maybe I'm the only one who feels this injustice?
