I Don't Like That Smile(2016)

Sono Egao Suki ja Nai

"You make me wanna mess up that cool, indifferent face of yours," says Ritsuki to Sumire in the gym storeroom. So begins the game between Ritsuki, the most popular boy at school, and his friends. His objective: to make Sumire, a cold, aloof girl who's rumored to sleep with anyone, his new conquest. As Ritsuki gets closer to Sumire, however, he starts to see her true face, which is far different from what her normally stoic demeanor would suggest. It's a hurt-filled lovestory of two hearts nursing deep wounds.
