It’s not rushed if u pay attention, it has been building up for many chapters
Unnecessary opinion
Don't get me wrong I still enjoy the manhwa and really appreciate the writing and translators' work
I'm just not a huge fan of Taker resurrecting him and then dying again since I've seen it before (spoilers ahead but I've seen it done similarly in Dine with a Vampire, acotar, tgcf) and it doesn't make the plots bad but it just seemed a little too familiar to me. Maybe there could've been other endings ofc but you're right that it's been building up for many chapters, so it makes sense.
Honestly the whole dying, time travel, resurrecting thing feels so rushed and unnecessary but ig if they're happy in the end...
