The guy leaves his friends behind just because the girl texted him and you can tell that he really cares about her.... I think he's at least going to be confused about how he feels about her. Maybe in the end he'll realize he's pansexual. But I'm 100% sure that this chapter set things up for some kind of confusion between those two (maybe one-sided from him).
Or maybe author goes completely in opposition of that and make him realise he's aromantic and/or asexual, but it would be less interesting in this setting imo.
