Warning!!!! Spoiler!!!!
How can i get photo 3 and 4 on page 11 in hiro's route
Just stick to hanging out with Atri as much as possible from the start of Hiro's route, you should get the scene simple enough once you get an option for a nsfw scene after going to the bar with him.
^ pretty sure that u also might need to get a perfect score on the memory game earlier on but don't quote me on that
