Haruurare:Achievements

Achievements
springEight basically means you can't have any girl with n Beauty as defense, timing this right is hard.

fullFlat, pleaseSensei and glassRunner may refer to having only one type of girl? (As in, only glasses etc.?) Or only one type of customer? But that'd be rather stupid.

luckyClover is a matter of reloading, and maxHeart will happen eventually.

endless may have to do with the amount of money you have. (You probably get it if you just finish the game normally.)

There's also one achievement you get for buying the 1.000.000 item, but I do not know which it is. (That's probably sanzaiBurst.)

I also saw something mentioned like "do not put any girl to work", you'd need to max out on the starting cash to see the ending like that.
