I thought this was a very unique read. The MC is both loveable and hateable since he shows a real human aspect of confusing confliction. He doesn't understand what he wants, who he wants, or what other people want but he still tries to make stuff happen. Granted, he has that manipulative side where he just assumes he knows best and then goes about sabotaging things he shouldn't be messing with.
Ultimately the ending was a bit of a bore since it ends like 99% of other stories with the MC and MLI being together after a dramatic declaration of love. I think it would've been a better story had Yujun dipped out and found himself for a few years but it also would have left the chance to follow up with a sequel so the other characters stories could be elaborated on.
TLDR: MC is an iffy character but has 4 guys all coming onto him--2 of which aren't even initially interested. The one who's most genuine (CHF) is treated like an annoying kid and when it gets all dramatic and looks like things are gonna end with MC unhappy, it pulls a 180.

The only one I car really think of is this

So~ The MC and his family are in debt to gangsters due to his father who we never see. Since working normally wasn't earning the Won needed to pay off his father's debt, he took a friend's shift as a host for guys. MC is coerced into sexy time but the main love interest (MLI) saved the day and offered the MC money to be his. Ultimately ends with a tug and pull relationship of "do I sell my body for the money? and/or do I love him?" all the while, MLI is dealing with his company problems and has to save the MC from being sold into sexual slavery, because of course...BUT in a surprise twist, the red-headed female friend of MLI actually saves the day by buying our little MC for 200mil Won ($200,000). It ends with the MC and his MLI together, frenching in the streets cuz PDA is awesome.
TLDR: Good hearted cinnamon-roll is entrapped by a bunch of guys wanting money but is saved by a rich guy who wanted MC's @ss instead. This leads to the usual rape/kidnap/revenge plot that is thankfully averted. Ends happily~

Idk if I missed something but out of all the royal character's we've seen, Emil (The Duke/Prince) is the only one who hasn't been shown acting evil. A cowardly mama's boy who play's along with the royal marriage--sure--but not "evil". I think he's a great add for comic relief since it shows not every royal is evil by nature but that's just my opinion.
The whole thing was a nice, smooth read with heartwarming moments and a touch of drama but unfortunately the manga got the axe by the producers apparently, leading to a bit of a rushed ending. Leaves questions, sure (like what happened to the original Yui after that look she gave? What about LipSweet's Yu-Chan? Does our MC find love?) but all in all, it's worth the read. (▰˘◡˘▰)
