//I have talked and drabbled about this plenty before, but take this as my closing headcanon of the night.
Yi has a great distrust and anxiety when it comes to hugs, or people being close in his personal space. Especially women. He has had experiences in the past where people have grappled him in order to stick him with knifes, most notably when he was younger and he was tricked into intimacy by a lady who only wanted to steal his possessions.
She stuck him with a dagger long enough to harm a lung when he was most lovestruck and vulnerable, leaving him to die. If it weren’t for his healing meditations, the dagger between his ribs would have killed him. So don’t be surprised if your huggy muse gets refused by him, or if he Alpha Strikes out of the way, or if he just draws his blade in response.
It takes a lot for Yi to let you into his personal space, and only few are allowed there as it stands. He’s too world weary and combat ready to be lenient in these sorts of things.
