Part 1- Hard Realization

After multiple attempts to pursue Zhan Zheng Xi, Jian Yi comes to a hard conclusion. Zheng Xi will never see him that way. Although his love will not fade away he will try to expand himself and have fun with other things or other people while keeping it away from his unrequited love. But what happens when Zhan Zheng Xi notices the change and starts receiving weird messages from an unknown number?

Note: may contain smut, fanfic of 19 days/19tian (not my characters) doesn't start at any specific point of the manga, and may have some weird turns cause I still don't know where it is going
