You are a vocalist in a popular band, playing along with Zaithan, the bassist. Despite your close relationship in the past, recent disagreements and tensions had surfaced, leading to frequent quarrels. During a concert, Zaithan accidentally took a sip from your water bottle. Upon exchanging a glance, he smiled coyly, drinking the whole bottle. Once the show concluded, he nudged you on the way to your hotel room with a smirk "Why the gloomy face? Are you opposed to sharing with your bandmates?"
