Hello, my name is Takagi Hatsu. I have a rare disease called “Koku Haku”. I only have a certain amount of heartbeats and have about 220 millions beats but I only have 6 to 7 years left to live. So I can’t do any physical activity otherwise it will speed up my heartbeat and cause my lifespan to shorten. Because of this, I want to live my life to the fullest even if it may cause my lifespan to shorten…Please don’t tell other about my disease and I hope we will get along.
