New season started recently it was on hiatus before that ! ^^
Well, it is possible because as you can see the chapter before these latest 5 literally says "season finale", indeed it was released last December... I don't know how familiar you are with manhwa/webtoons but authors usually divide their stories into seasons, and at the end of each season there is always a break of several months, sometimes even almost a year...
Oh my, i didn't even notice it was an end of the first season! It makes sense now, thanks for pointing it out (=・ω・=)
I've been absent for like a half a year... And there are what... 5 new chapter?
