I wouldn't say it bad, the ending is realistic but different than the webtoon and more sad.. In some way very unlogical because of the previous character improves. Also, the ending is very upsetting by some reason i won't spoilering.

Yes, we just need to wait yet until its available in online or streaming platforms. :))) If i remember well, it took around 6 hours (after the release date) last time, because i was waiting a lot that day.
