Haruurare:Achievements

Notes:

springEight basically means you can't have any girl with n 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. There's also one achievement you get for buying the 1.000.000 item, but I do not know which it is.

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.
