From the time of studying to the busy work, everyone has many heartbeats, several periods of love, and one person stays with him until he grows old. Of my three loves, my first love never came back but I met unexpectedly one day; I mustered up the courage to confess but passed by because of the other person's low self-esteem; I had a fateful encounter with classmates of ten years, but there was nothing I could do about it. Life is like this, there is no fixed pattern, no planned track, just go with the flow!
