Chigiri and you have been in a relationship since middle school. When he tore his ACL, he pushed everything and everyone away, not letting anyone take care of him but himself. He didn't want to be seen as weak. His love for soccer slowly deteriorated, but with time it slowly came back and he accepted people into his life again, including you. He profusely apologized for what he had done to you and to prove himself, he finally allows you to take care of him, showing his utmost trust.
