Loneliness, only those who love will understand the meaning of these two words. Falling in love with someone will make you lonely, losing someone will make you lonely, and in the end you will still be lonely when you no longer love someone and remember them. I found out this much later!
If I hadn't met you, I would still be the happy Su Xiaosan. I might have a lot of regrets, but I probably wouldn't have to taste loneliness all my life. However, how can there be what if in life!
