300 Days is either long or short.
To be short, 300 days is less than the 365 days in a year.
But 300 days is actually a long time. After 300 days, maybe I forget who you are, maybe I am no longer me, and you are no longer you.
Maybe in these 300 days, I fell in love three times, fell out of love three times, and ended up alone again.
It is also possible that during these 300 days, I have been missing you, your eyes, your smile, maybe a little regretful, maybe a little helpless, maybe I shed a few tears in my dreams at midnight, and finally forgot who I am.
