I don't think is gonna finish anytime soon, the mangaka still updates and is active about it on twitter, she is selling a lot too.
The plot is Slice of life so it can go on a lot, telling us about each step of their relationship, maybe she'll continue until they grow old together and it works.
Personally I think is fine, BL's aren't long, this is one of the few works that is past 5 volumes and still going strong and its fine.
If you want to read it is always going to be here, if you prefeer other stories or shorter stories theres a lot of options too :)

No issue with long-running stories at all! I started the Finder series like 20 years ago, also Sakaiichi Hatsukoi, or Koisuru Boukun But since I don't read as much anymore as when I was younger, I do hesitate starting new ones that might only end when I'm 50+ But I'll trust the comment above and will give this another shot now!
Can someone please tell me if this will come to an end anytime soon? I started reading it like 10 years ago, still remember loving it but didn't have the time to continue back then until I forgot what was going on so I decided to re-read after it's completed... Been waiting for that time to come for over 5 years now
