Okay guys for anybody confused. There's links below to read the chapters 11, 12, and I believe 13. So what I'm getting from this (I'm bad with names) Yuta and the red eyed guy have history from ten years ago. And I am predicting that Yuta put a lot of trust into the red eyed guy. In the chapter the red eyed guy was like "are you doing this because I didn't pick you up back then?" meaning that in a way he didn't show up when Yuta was in danger so Yuta held a massive grudge going through like hardship to the point he had to like marry an older man. Also we know yuta's husband died which is how Yuta was the one sitting on that chair (probably inherited something) and not who red eyed guy actually expected. Anyway if you guys read the chapters from the links below you'll see that yuta wants to use the red eyed guy (don't know his motives yet) but it's clearly the kinda trope where it's "i use you, you use me" and they'll end up together perhaps?
