Nice to see my boy Ryouta getting some character development and now helping uplift others. As he said, he was very lucky to meet Emily best girl and thanks to her kindness he became a better man and now he'll spread this same kindness to other people and make them strive to be better version of themselves.
In the end this proves again that Emily is indeed the bestest of best girls and Ryouta needs to marry her as soon as possible.
