Waiting for Happiness II

May has always felt something for Son ever since they met, but they remain stuck in the friend zone as she is afraid to make a move. One day, May finds out that a beautiful girl has taken an interest in Son and finally decides to take “action.” She works tirelessly to make a card for Son to convey her feelings, but ends up accidentally losing it. At a loss, May rides around aimlessly on the MRT, but thanks to the help of Greene, Stationmaster Little Black, Cat Boss and Sakura, the card is eventually delivered to Son.
