On the Contrary 

Ban Ji-Un is loved by all. No matter how chilly someone's exterior may seem, she always finds a way to break through. That is, until her classmate Lee Yu-Seon comes along. For some reason, Yu-Seon ignores Ji-Un’s every attempt to win her over. Ji-Un is dumbfounded that, despite her best efforts, she just can’t find a way to weasel her way into the standoffish student’s heart. But when the two have an unexpected encounter, they just might discover that it’s never when a girl is looking for love that she finds it. On the contrary…sometimes it comes from the place she least expects. (Source: Lezhin US, edited) Note: Includes two extra chapters.
