You've told us who she can have content with, but nothing about who
you want to see Yoon with. So obviously the dev team will need more details of what you want.
Since you're new (welcome, BTW), I'll give an example. Since this is a female MC, many of us that are after lesbian content flocked to the thread. And when we were forced to witness the scene between Michelle and Jospeh, many of us threw so many hissies that the scene was made optional. Hence the "Pure lesbian route" that currently exists.
Point is, the dev team here (shout out to
After Choices and
Stella Ko) are unusually receptive to member feedback. If you tell them who you want to see content with, chances are they can give you a yay or nay as to whether or not it's reasonable to expect action between them and Yoon. Male protag has pretty much already been ruled out, for example, because that tends to be a dealbreaker for some people for some reason. But only because people mentioned specifically that was what they were after.
