Hajime entered a boarding school when his father remarried three years ago and is now approaching graduation and adulthood. He thought his youthful feelings for Mihana had faded, but seeing her run toward him with a smile after the ceremony brings them rushing back. Thrilled by their private celebration, he struggles to suppress his desire while escorting her to a hotel. There, she kisses him gently and calls it a gift for the now-adult Hajime, leading him into a new grown-up experience.
