This is my first campus romance novel. It was written in 2012, the first year after I graduated from college. However, due to severe procrastination, it was not published until 2018. This is a fresh campus love story about friendship, love and family that takes place in a cafe and is derived from sending future letters. This story is warm, practical, simple, not impetuous, and slow food. Like a cup of warm water, not rich and fragrant coffee, not exciting cola, so healthy, so ordinary, it is the story that happens around you and me.
