In some parallel universe, there is a Tim. Like most Tims, his idol was the second-generation Robin, and he volunteered to become the third-generation Robin.

Tips:
1) The cp is yet to be determined (the author doesn't like any cp) and should not be abused (the author wants to write cookies).
2) The plot line is confusing and OOC is common
3) Integrating DC and Avengers
4) The author has no brains and has not saved the manuscript. The fate is even worse.
Concept: Life is always full of uncertainty and hope
