Is it complete? It says ongoing though ?
It's not. It's in the middle of 4th season rn
I have seen this being tagged as "completed" then "incomplete" again for quite some time now. Back then, when it was still tagged as shounen-ai, I remember that I have finished reading it as it was already tagged as "completed". That's why I was shocked when I saw updates and the tag was changed to yaoi. I was like HELL YEAH I COULDN'T ASK FOR MORE. I guess the translators or whever the uploader is didn't know that time that the author would add more seasons.
I read this before when it was still incomplete and at that time it was still tagged as Shounen Ai. Feels good rereading. (▰˘◡˘▰)
