First time i hesitate because some of the comment is negative about this, but after finishing it in one go i can assure you this is some good shit.
Yes it has slow pace, nothing grand happen. Even tought she got upper hand for knew the future, she doesnt do anything that feels so unrealistic like other overpowered female lead manhwa (scheming, assassination, bussiness, friendship power, harem, etc). She's just a teenage girl who wants to experience the outside world, not wanting to repeat the same mistake.
This review is for 1st season, i hope the 2nd season is better because the battle has just started
(Sorry for typo or misgrammar, english is not my 1st language and this is my first time reviewing something 😘)
