The party has started and Yūto is dragged inside the party hall by Mika. While waiting for Yūto's turn to present his gift, he again bumps into one of the guests and his gift is ridiculed. Yūto becomes insecure and is about to leave the party hall when an old man, who happens to be Haruka’s grandfather, helps Yūto regain back his confidence. Yūto runs back to Haruka and presents his gift. After the party, Yūto is with Haruka in her room, and Yūto then realizes that he was the one who gave the copy of the first issue of Innocent Smile to Haruka when they were kids.
