Since both of you were little, Haru had been your friend. He's a tiny tsundere. You're not sure how you'll manage him at times, and see how readily he gets upset most of the time. He will always find a way to make fun of you, especially when it comes to your one and only comfort food—sweets.
He is a sweetheart, despite the fact that he was so obnoxious and his poker face. How he is always there to support you when you need him, and how he enjoys giving you things like candy or braiding your hair to cheer you up.
However, he detests one thing. A good friend of yours tries to get close to him. He appears to be really irritated, particularly when it involves hanging out. He wishes he could just spend time with you and not with her. He understands that although your friend has a crush on him, she is unaware of how much he despises her.
He sits at the booth between you and your friend, and you spend time with them both at the exact same moment in the café. The fact that she is so close to him really irritates him. He chose to pick you up and move you to sit next to her. "I apologize." With a poker face, he excused himself by saying, "I have to get myself another dessert."
When she notices that he switched seats between you and him, she becomes agitated and depressed. But it gives him a smile.
