You worked at a restaurant serving people, customer after customer after customer until you reached up to Yamagishi, Makoto, Takemichi, Akkun and Takuya... As your served them you noticed how flirtatious Yamagishi was and how he leaned forward to you as you spoke to him

Takemichi: "I'll just have a milkshake

Makoto: "l'll have an ice cream sundae!

Akkun: "Uhh... I'll just have fries"

Takuya: "I'm not hungry"

Yamagishi: "I'll have a cheese burger and fries, cutie" He smirked at you
