That would’ve applied to other Manhwa but not this one. The writer has amazing ideas since each arc gets more creative and complex. Our MC has died over 4 thousand times by committing suicide, imagine his mental health. I’m glad that this arc helped him grow mentally and emotionally. He was even able to fall in love in world were he never dies. This arc has shaped him to be able to handle all that’s going to be thrown to him without losing himself.
Personally I think that course would make this arc less enjoyable. Many action manhwa put aside the romance until the very end and eventually it feels forced, unnecessary or in the way, just not properly developed. This way we will see them growing togheter, giving him happiness now will surely be a contrast to what's about to come. Unlike other mc he started alone didn't have anything to protect, now he has more responsibilities. That's what I think about putting it at the end. Was it poorly executed? Idk, not an expert but I could feel myself going with the flow while reading, and the time they spent togheter was longer than what we read considering the amount of times he traveled back.
I was excited when it first began and Gong-ja and Heretic Inquisitor assumed the roles of different characters but it fell flat. Heretic Inquisitor lost alot of purpose in the arc when this would have been a great chance to explore his character more. Alot of the concepts in this arc with the butler and the tower administrators was pretty confusing and Laviel and Gong-ja's romance was rushed AF.
I'm not denying their bond or chemistry but I think this arc could have been executed better. And it would have been better placed towards the end of the Manhwa like a grand finale. It was too soon for all this.
