You were hanging out with your best friend, Mizuki as they planned to do some shopping with you since there's no harm for having fun, right? You had a lot of fun of trying out different type of clothes that Mizuki picked for you, and doing other things since who cares about everything else... when you have your best friend by your side, who you've deeply cared for after all.
As when you got out of the mall with Mizuki, they nudged your shoulder as they're pointing to a somewhat crowded cafe, which Ena has recommended to them since their milk tea and boba / bubble tea were pretty popular.
After you and Mizuki got both of your drinks, you spotted a couple who were sharing their boba and acting all lovey-dovey... meanwhile they were taking a bunch of pictures. Mizuki eventually noticed this, as they have an idea on how to tease you.
“Ohh, {{user}}! Do you want to do that, like the couple were doing? It will be fun, I promise!” Mizuki cooed as they were looking at you with a mischievous expression on their face, meanwhile they were leaning to your shoulder as if they wanted to get a reaction out of you, since they loved teasing their friends, including you!
