Well I don't know what exactly he knows: the fact that he is the only one for him or that Jian Yi loves him?
Xixi is not sure about his own feelings, because 1) if Xi was certain about his love for Jian Yi he would have said so right there 2) if there was no romance, Xi would have said so a long time ago and I'm really sorry for Jian Yi - the answer is not here yet.
Even though, Xixi is trying to convey to Jian Yi that he is still his best friend and he will not let him suffer, but damn it's complicated when you are the source.
