Lessons in Love [v0.53.0] [Selebus]

Spoiler: Cheat codes as of version 0.22.0
goodhomie = undo betraying Rin.

rosebud = increases affection with all girls by 100.

lagfix = resets the call stack which an early version of the headpat system caused to pile up and cause lag. Doesn’t mark save as a cheater.

floor1victory = make it so floor 1 won the dorm war.

floor2victory = make it so floor 2 won the dorm war.

dormwartie = make it so the dorm war resulted in a tie.

funinthesun = resets the beach event and makes it trigger the next Sunday.

fingeryourniece = resets Ami’s events ‘No One Can See Us’ and ‘Important Things’ and gives the message “You now have the opportunity to be a better uncle.” Guessing there’s gonna be consequences to these events in the future.
This cheat only works if you haven’t completed the Christmas event yet (specifically the event named “Fireworks, Chicken, and the Innate Fear of Death”). Attempting to use it after the Christmas event does nothing, not even marking your save as a cheater.
If your playing the censored version, replace the word niece in the cheat with whatever the censor replaces it with. I’ve never played it, but the cheat is set up to accept the alternative.

iwillalwaysloveyou = increase Ami’s lust by 100.

bubblewrapprincess = increase Ayane’s lust by 100.

likemotherlikedaughter = increase Makoto’s lust by 100.

heartofgold = increase Chika’s lust by 100.

atreefallsintheforest = increase Futaba’s lust by 100.

supermom = increase Sara’s lust by 100.

thouartsick = increase Haruka’s lust by 100.

youonlyliveonce = increase Kirin’s lust by 100.

openrelationship = increase Maki’s lust by 100.

shiningstar = increase Niki’s lust by 100.

seemeafterclass = count Chika’s ‘Detention’ lust event as having triggered.

wheredoesthetimego = “100 Days pass while you sit at the computer. It’s almost like real life now, isn’t it?”
That last line is straight out of the game. I thought it was funny enough to just copy/paste.

Spoiler: Possible effects of using cheat codes
Using any of these cheat codes except the few noted will silently mark your save as a cheater. As of version 0.22.0 there are no repercussions to using these cheats. However, this is a denpa game (see horror tag). As such, there is a very real chance some very bad consequences will be implemented in the future for cheating. I recommend playing without cheats first, then, if it’s too much of a grind, using a save editor instead of these cheats.
Cheats are entered using the “Computer” option on the weekend.
