Hi! Thank you for the kind words about the game <3
Most guides are on the discord if you want to check it out: https://discord.gg/keDm9nZSxp
About the host club, focus on abilities and try to make a good combo, if you have Yuna, Sonnet or Rayla abilities make a team around them, to get abilities you need to get the same girl multiple times (Each time there's a growing 15% extra chance to unlock an ability)
For the frog game, yeah I understand it's not the easiest controls sorry, try to be very fast, instead of going for accuracy try moving and releasing often.
Finally, for Max event, is an achievement you unlock by answering perfectly like this:
-There's nothing I'd like more
-I'll make sure to have all kinds of dates with you
-I wanted you to have a nice memory
-You deserve to be happy always
-Come here, I'll cover you with my jacket
