MY TSUNDERE SISTER

University summer break is drawing near, you and your girlfriend go back to respective hometowns. Your cousin, whom you haven't spoken to in years, knocks on the door of your home. She'll be staying with you temporarily for holidays. A tiny misunderstanding upon reunion leads her to label you a pervert. Once she learns you already have a girlfriend, her attitude grows more awkward and tsundere. Thus begins your bumpy cohabitation. Familiar streets and old trinkets slowly unlock long-buried memories. Your bond gradually shifts into something tangled and delicate before either of you notices. Then one day, you accidentally uncover her hidden secret identity... Now it's your turn to stand up for her. Just like you did all those years ago when you were kids...
