Select options that minus your chances with all other characters apart from Aaron
Visit Aaron everyday after work.
Save up to buy CD first as that will help with writing poems at home and writing course. Please take note that the higher your morale score is the more successful you are in undertaking these activities.
Borrow books on Monday and Fridays but in between do buy books from the Mall and read them to Aaron.
Buy the 'plushie' and enter the room.
Find the cat as this helps with the romance and then go home straight away and write a poem. You'll be amazed.
Visit the Disco because that is where you'll get the Aaron and Amy song scene.
You want to particularly avoid the scene where you're at the library and found the book Aaron bought you, that's a big No No which is why saving from time to time is good.
Also, if you're at the GYM, there will be a poster that Aaron likes, you'll need to have $75 dollars to buy it but all is not loss. I managed to achieve 99 romance points and 100 points romance scores with Aaron so you can do it too.
