The 2nd part receive a lot of flack due to it focusing on romance more, and believe me, I was also one of those people who weren't on board with it...
But the thing is, I love the second part. It's great! The two love interests are interesting, fleshed-out characters. The relationship developments are not rushed or forced, but gradual and impactful. And above all, Nari's characterisation isn't sacrificed for the sake of a romantic plot, she's still the Nari we know and love. It does all of this while still remaining extremely engaging and entertaining!
Though, I think the only main gripe people have with this part is that it tends to shift the spotlight to Nari and we see fewer insights on Mirae and Seonji.
However, I liked the fact that we were able to focus on Nari more in the 2nd part!
Since because of it, we're able to get a clearer view of how much she has developed and grown as a character.
And lemme just tell you: it's SUCH a contrast to early part 1 Nari!
For example, we see of how 2nd part Nari still can cry and becomes stressed about things, but then she deals with it and fights back!
(There might be a misinterpretation that I dislike Mirae and Seonji because of liking the focus on Nari: no I love them lmao, I do miss their insights but the focus on Nari is giving us so much too. Mirae and Seonji focuses are definitely gonna come back once Yuna comes back...! Gosh I miss Yuna lmao)
And yeah, that's that! I might go back and edit this to perhaps word it better, as I really want to convey that the second part is genuinely great. Do give it a try!
