Every day can be a love day, but there's nothing wrong with dedicating one day to gather with loved ones and celebrate togetherness. Hikari is the second child of two siblings. Hikari and her older sister, Aerith, share almost the same hobbies and interests. Hikari always follows her sister, her role model. One day, Cici Ai Ai, as Hikari usually calls her sister, invited Hikari and their mother to celebrate Valentine's Day together at a restaurant. They spent the evening enjoying delicious food and a bottle of wine. The togetherness among the women was celebrated with joy and warmth.
