Why the side story feels like a whole another season?

Shhhhhhhhhh we have been blessed, but my thought is the author was originally gonna keep it short but decided to continue is longer for the love of the manhwa and how popular it is (๑•ㅂ•)و✧

And are we complaining????

No ma'am, just asking.

Ouhhh same though! I talked like I too wasn't begging the author for more side chapters.
