I dont think the letter was meant for Jian Yi. I mean why would he tian entrust red head to give the letter to jian yi when he knew that Jian Yi and Red head are not in good terms; it could cause misundertandings or jian yi might not believe red head, so that would be a big risk for he tian. I feel like the letter is for other person who's secretly monitoring Jian Yi, it could be his mom or his father. But if those guyz are really Jian Yi's father's hooligans, then why did They still ask Zheng Xi? They are not familiar with their target at all.

I think the uke really likes the rich guy and he's just using Tomoya to escape from his true feelings. He keeps telling himself and Tomoya that it's just for the money. His way of denying his feelings is by having sex with Tomoya.

Agreed

Now let's see if rich guy lets Keigo keep seeing Tomoya on the side or even as a threesome
