I think Ian thought Eunsan only wanted to have sex with him because he's the hockey star and played well, but because Eunsan showed that he preemptively thought about having sex with him even before seeing him play Ian felt a bit reassured that Eunsan might actually be interested in him outside of him playing well.
How is it appropriate to tell someone you wanna hv sex when your partner feels insecure about your feelings for them and wants to be assured? It'd make me doubt our relationship even more. Well my mom always used to say "It's only a fictional story"
