He made a vow to her family so I don't think there'd be much (if any) 'harem' drama.. maybe season 2 will introduce outside forces/powers and 'test' their love through separation and all that melodramatic stuff lol
I really fell in love with the art though so I'm 80% excited and 20% anxious of a season 2 😆😅
As always, thank you translator-samas! 💕
