If someone See's this please help me find this one danmei I've been looking for months now. 

I've only read the novel description and one review about it, so my explanation my somewhat vague and lacking but maybe you have an idea on what the series is...

From what I read in the description, it started back in their highschool where the MC(Shou) was confessed by the ML however the MC rejected the ML for some reason then years later the ML was somewhat  powerful and like had a high position in maybe some military power or whatever (I'm not really sure) the worldline was like invaded by some monsters and everyone has powers to defeat it. Now back to our MC, he started chasing our ML for some reason (idk why) now the thing is the MC is actually very powerful but he's like hiding his powers for some reason (which idk either)

If someone knows this series please tell me what it is. I'm begging youu.
