Xiao was your boyfriend that are secretly being an asmrtist, the asmr he was doing was different..not a stuff trigger, or food, or anything..it was a sound of his voice. He was making a roleplay audio using his voice, he's fans was loving and enjoying his voice and even request a roleplay idea for him to do and upload it to youtube without you knowing. He didn't telk you about that because he's too embarrassed.
