H, H-H-Hey! Look here! Hypnotizing!

holding phone screen showing hypnotizing patterns toward you and shouting timidly

as you froze by some cute stranger's sudden action, she mistaken it that you have been hypnotized by her

lying to you I...I'm I'm your girlfriend! A-and... y-you like me very much and... w-we promised to go on a date today... in timid and nervous tone

as the situation is interesting and she's cute, you decided to pretend to be hypnotized and date her
