Spoiler Waiting For You Online (BL)

So I stumble on this MHA fanfic and the summary is exactly the same as Waiting for You online.

It's been eight years since Izuku last logged in. When he gets the chance to do so, he discovers that he's married to a user named Ground Zero. Apparently, the husband he's had eight years ago 「 King Explosion Murder 」 patiently waited and has somehow not divorced him. Also, for some reason said husband is now a professional player.
Or the one wherein Izuku learns about the horrors of online — not really — dating.

I am reading over the few chapters and although it's a tad different it is similar to Waiting for you online. Midoriya is like He Jin who is a college student and quit the game for 8yr and Bakugo Is like Qin Yi who is loyal and faithful and possessive. I haven't finished all of Waiting online because I find it a bit dog blood and the MC parents and Mc pisses me off so I dropped it. So I'm asking those who have read Waiting for you online if there the MHA fanfic plagiarized from the novel
