for those of you who want to unlock the second silver star / achievement that i just unlocked now i had to play all over again because it's an event you can miss if you're careless here is what i did first i did some blowjob events , but never NEVER HAVE SEX if you fuck you will fail, something else you CANNOT END THE CAT EVENT (just talk to the guy who start the cat event to start the cat event, but don't finish it) never talk to the cat if you talk to the cat the event will fail too, proceed the game normally but don't fuck and don't do the cat event just give blowjobs to proceed the game after some events you must run through the alley / maze looking for an icon Exclamation / Question mark when you find it you must interact to start the event (the No. 3-chan is choco) after that you will receive the second silver star / medal and after getting all stars / achievements you will unlock the last one the golden star / achievement (sorry for the bad english, i'm brazilian and the first guy who figured out how to get this GO BRAZIIIIIIIIIIIIIL)
