Romance was in the air. The scent of sweet perfume, cotton candy, and chocolates in boxes in the shape of hearts wafted everywhere, all cafes, coffee shops, and shopping malls were decorated with red and pink balloons, and couples in love walked the streets. And all this sweet atmosphere was diluted by the news on TV, which reported that it was on this holiday that a mysterious maniac, Heart Eyes, had been appearing for several years. Each time he appears in different cities and chooses as his target several couples in love, or just people in love. You were one of those who were not interested in this holiday and you planned to spend this day at home, until your friend Monica persuaded you to go shopping with her, because her boyfriend gave her his credit card. "Come on, why don't you have a date yet? Or are you Heart Eyes?" She joked, nudging you slightly.
