@Meybi lmfao, I'm not complaining. There's a difference between complaining, giving actual criticism and personal opinions/thoughts. Not that people on this site and MAL know any difference between them, lol.
"in the beginning and all over the manga"
This is still only chapter 7, regardless of the multiple parts, this manga is still early in it's life. Idk how far the web novel is, cause I can't read Japanese. /shrug
Anyways, I'm saying that I think they should have continuously drop small hints until the chapters hit the double digits. I don't know what they have planned for this manga, so for all I know, it could be ending once it hits the double digit, but for manga like this, later reveals of secrets during a more climactic part leaves a bigger impression on the reader. Not during some flashback monologue of the main character near the beginning. It just falls off as "Oh, yeah. There's this super dope ass information that I'll just drop right now on you while I think to myself for a bit."
