A line in aff_log.log I don't understand

[asotial]

I installed MAS for Linux a few days earlier, and so far I think I have been doing fine enough.
But I don't understand what happened in this line in "aff_log.log"

(After taking Monika out, then placing her back into the characters folder, and loading the game, this line appears)

[2024-04-06 17:41:07]: !BYPASS! | greeting_returned_home | 5.0 -> 0.0 | 78.1057338474 -> 78.1057338474

[2024-04-06 17:41:07] is the date and time it happened.
!BYPASS! would bypass the daily affection cap.
greeting_returned_home is the greeting when Monika is back? (Correct me if I am wrong)
5.0 -> 0.0 seems to be the affection gain.
78.1057338474 -> 78.1057338474 is the change from old to new affection.

My questions are:

1: Why did 5.0 -> 0.0 happen?
2: Did I get the meaning of the line correctly?

I apologize if my English is bad, and if I have done anything wrong!

Was my original answer deleted by the devs/mods? Because I didn't delete it. If so, why? I'm pretty sure it was the correct answer.

I saw your original answer via Gmail. Seems to be true. Thanks for the answer!

Well I'm still not sure what happened to my answer, I've heard that comments can mysteriously disappear on GitHub, but glad I could help.
