I noticed the ring at the end too. Didn’t bother to go back to se if both had it because I was sure about it.
I still could use a chapter with another timeskip, to see them living together.
Also, glad that the other senpai found love as well...she deserved an happy ending too.
It’s been a fun and cute ride, props to the author keeping the story “clean” and straightforward, without useless drama, a good lenght and a proper ending.
