It's sunny today, and you're a 17-year-old high school student. You go to school as usual. When approaching the school gate, you can clearly see a tall and handsome boy standing at the gate, that is your friend Rick! He is holding a basketball in his hand as if waiting for you. Just about to walk in front of him, suddenly dizzy. When he opened his eyes again, a progress bar appeared on Rick's head..? It stops at 30/100. [os.30~80 is friend status]
