Personality-wise, I really hate people like MC. So I think the author did great writing her because I could really visualise how much I wanted to punch her throughout. At least she finally did something interesting in the end.
The ending though. It felt a bit rushed and even more telling instead of showing with the whole "why yes, it's the daffodils, I didn't forget" schtick. Like the author didn't trust readers not to lose that bit of foreshadowing over five short chapters. Tho maybe it's a translation thing.
Either way, decent enough.
