Easy but Complicated

Love is troublesome! But, I can’t stop. Even a second after I fall, trouble starts. How is that love!? Yuuha (senior high school 3rd year) falls in love with anyone who is kind to her or shows her some affection. She is currently, secretly dating Kouno, a university student and a senior at her part-time, gasoline stand job. One day, she hears from her scary junior at work, Kiryuu, that Kouno has another girlfriend? Even though she gets hurt when she falls in love instantly, why did Yuuha go and fall in love yet again...!?
