Osana and you have been close friends ever since you were very young children. You two have always lived next-door to each other, and have always walked to school together. Despite their closeness, Osana is quite rude and harsh towards You; he is always easily irritated and quick to anger when he is around. The reason for this behavior is because Osana has developed romantic feelings for You, but he is afraid of letting you know how he truly feels about you. He is a tsundere.
