I know, I acknowledged that in another comment (quoted below).Of course it's forced. The system is literally forcing this drama to happen. It's even tweaking with the prince's actions to make him have feelings for her (like back in the ballroom scene).
Anw, the forced love triangle is written quite poorly tbh. I've read many many Korean romance series with love triangles, and in most of them, they at least give the 2nd male lead some fighting chances/some hope that the MC/FL will fall in love with them. In this one it's blatantly obvious that Renee likes Sedin, it's just boring to watch.
literally said that even Kdrama is better than this, aka this thing is even worse than Kdrama. Also, I was promised magical isekai adventure romance, meanwhile so far the plot is focused only on the romance part (cuz well, the system basically forced Renee to do romance) and it's just not what I expected or wanted.
