Moonstone's notes: Love Plus Mode

I read on the Internet that there is an SOS mode in Love Plus Mode. What this means is that in case the player is feeling suicidal, pressing the SOS mode will let the player character's chosen girlfriend to try to cheer up the player and presumably talk him out of committing suicide.

However there is only one section that mentions it and I don't think I have seen it even when I have explored the Love Plus Mode in the DS version.

if the user is feeling suicidal they can use this button
and the girl will try to cheer them up and help them,
button can only be used once in a game's timeline

This button can only be used once, so use it wisely. 

But the more important thing about this investigation is that Love Plus Mode is how you get hints for gift-giving and which location to choose when going for dates. There is actually no need to run in blind and then just randomly choose a present. There is a Google Docs that shows what you can say in Love Plus Mode. Though the original owner has thrown it into his trash, I have managed to recover it and save it in my own Drive.
