He never betrayed her, he's always there for her AS A BESTIE, yes they become best friends kinda like how Sancha and Adri are, he's always such an emotional supportive person towards Adri, quickly to fight anyone who says something negative about her, and if you ask me it seems like he genuinely likes her but would never make a move cuz she Alphonso's woman. BASICALLY HE NEVER DID ANYTHING WRONG THAT WOULD MAKE ANY READER HATE HIM, and when those moments are finished drawing out in the webtoon then people are gonna start shipping them💀. But they're js besties and that's that period. Ps. Don't like Ceaser!!Spoiler text.
