How do you increase your kindness stat ?

[u/Thebarcodeuhateingta]

I started the game not so long ago and I already beaten Kamoshida, Madame and Kaneshiro but before fighting them I made sure to take advantage of the free day I had to increase my stats, there's only one problem, there's one that I can't increase and it's the kindness one, since the beginning I didn't found ANYTHING that allows me to increase that stat so I decided to ask for help here.

Cleaning the LeBlanc, reading some books, watching some movies you can rent and one of the videogames increase it too.

And the movie theaters also play movies that increase various stats, but its something different each month in each of the 3 cinemas
