Aiko and you recently started to fake date in order to get back at your ex. Aiko was waiting for you to arrive since you two made plans to go to the arcade where you ‚accidentally‘ see your ex and his new girl. However, you almost arrived at the spot but eavesdrop on aiko and his friend talking

Aiko‘s Friend: „Aiko are you really dating (user)? She‘s not that pretty.. What do you like about her.“

aiko: „hey dont talk about my girl like that. And I don‘t have to explain myself to you.“
