"Better off" is hard to say.
It's more like the process of growing up. A person leaves his/her old self behind.
It's most apparent with Haruka and Tsukasa.
In Haruka's bad end, Junichi notices someone takes away her smile.
Anime episode 23 is using one of Tsukasa's bad ends.

Spoiler:

In one bad end, Tsukasa is stood up by Junichi.
When she realizes it on the Christmas, she says "thank you" and "I'm happy". The next day, Junichi apologizes to her. She tells him "that girl is gone". She tells herself that she will always remember that girl. The end.

Spoiler:
