I had the same question before I read this. 121 chapters is a lot and the summary didn't really draw me in that much.. But I highly recommend it! Quite a good read.
I finished yesterday, at first I was about to drop it because it's too slow a first and I was getting bored, but I'm so glad I did not drop it cause it's so fluffy and cute! so wholesome!
121 chapters... is it worth it?
