Can you help me?

I'm searching for a boku no hero academia doujinshi! It's a tododeku one, it starts with them being in a stablished relationship way ahead in the future, when they are already professional hero's, but Midoriya gets replaced with younger Midoriya! So this deku doesn't get that he's in love with Todoroki, it's a little sad ╥﹏╥! I remember the whole plot, but that would be spoilers!! You can follow, I will be searching too, bc I don't remember if I found it here or on myreadingmanga jaja Thank you in advance!
