of course! you need get three checks with Lala, which correspond with three dialogue choices during the charades section of the game.
the first one is when Lala is suggesting you play charades with her. you need to select:
"I'm not really good at charades... are you sure I'll even be of help?"
the next option is later on, during the actual game of charades. it'll be the second round, while she's doing the balancing act. you'll need to select the dialogue option:
"Balancing on a ball for a performance."
and the third option is during the third round. Lala is brushing her teeth, but youll need to get the answer wrong again. for this round you'll need to select the option:
"Eating something she had to cut up, like steak or something."
these are the only options that matter when getting the good end as long as your affection isn't completely full or empty!
let me know if you have any more questions! I'm sorry i made it so difficult to get the good end
