I’d like to point out that Fuyuhiko Kuzuryuu, the boy who so adamantly tried to convince everyone that he had no connection to Peko Pekoyama whatsoever, ran like a fucking bullet to her side the very minute he saw her in pain.
He didn’t wait to come to her in secret and let someone else take care of her. He didn’t even downplay how emotional he was. He held her tightly despite the entire class being in full view of them. He threw away any secrecy without a second thought. He couldn’t handle the thought of anyone harming her, and leaving her side would not be an option for him.
Peko might be his protectorate, but Fuyuhiko would do the exact same for her given any chance. They would both sacrifice anything before harm came to the other. They have a deep bond that revolves around the both of them loving each other more than they love themselves and wanting to support each other no matter what.
The both of them may have trouble expressing their emotions verbally, very understandably so, but their actions speak volumes and I think that’s a beautiful thing.
