The power dynamic was already fun and interesting between them, the author could've just escalated with Oono himself growing dependant on Kureshima's narrations rather than inserting an SA scene to prove Kureshima's attraction to Oono. Had a lot of potential but after the SA, things are all poorly paced and leave me unsatisfied.
I don't get into stories for a happy ending so I didn't mind how fucked up this cliffhanger was. It's character accurate for the seme honestly.
Yoshiki has BEEN hoping for Tsukasa's downfall because he feels insecure as an Alpha. He carried that resentment for years, probably knew what he's doing would change Tsukasa into an Omega, kept pretending it's 'love' because he knew Tsukasa was all about fated pairs back then, and now baby trapping Tsukasa so his family would DEFINITELY be ashamed of him.
