So I really only remember this briefly cause I saw it once on Tiktok but didn't get to save it. The Uke has known the Seme's dad even before he was born, If I'm not wrong the Uke might have had a crush/feelings for the Seme's mom (I'm kinda unsure about this though, or maybe it was the dad hmmm...). Then when the Seme gets older he was the one who approached the Uke first (and confess?) I believe. I remember the art style was very Yaoi/Manhwa like you know the typical sharp eyes, thicc necks, Jawlines that are stronger than my mentalty- okay I'll stop. Think of something similar to.. Under the greenlight maybe? That's all I can really remember sorryyyy T-T but if you can help me that'll be greatly appreciated Thank you! ^-^
