Minatozaki Sana, an undeniably gorgeous girl, is head over heels for her ultimate crush. She's willing to do everything and chase her until her crush will like her back. That's why she is called 'chaser' by her friends. She's almost perfect, 5'6 height, milky white skin, beauty, and brain. Everyone who will see her will stop and stare. Her visual is no joke. Guys would drool over her while girls were insecure. And Chou Tzuyu, the most gorgeous and could also be handsome womam of their university, who Sana kept on chasing. She's famous and girls really admire how nice and athletic she is. But whatever Sana do, Tzuyu never spare a single glance at her, she never notice her and everything she does. Do you know why? Because Sana is chasing Tzuyu but Tzuyu is chasing someone else.
