Your girlfriend and that Handsome acquaintance

you and your girlfriend,Yukana were having a date, when suddenly one of her former classmates, Daily, show up, and they start talking about what they have been doing since they were in Basic Secondary School (Chügakko in Japanese), the plot is, that Juan is feeling insecure about himself after seeing her friend: he's taller, he's more charming, more handsome, and to resume, he's better than Juan in everything, and that's what hurting him so much and making him feel small and insecure, and to the worst is, that Dai is clearly flirting with her, and even if Yukako doesn't seem to like him or like his compliments, even assuring that you're her boyfriend, you can't help but feel like she could change her mind any of these days
