In order to get this achievement, you must do a few things:

- You must confirm all of Emily's beliefs, tell her that you do not drink, you're a virgin, and that you do not want a family after college.

- You must tell all of these things to Evelyn as well, so basically oppose all of Evelyn's beliefs, make sure not to lie. If you lie at all, you won't be able to get the achievement.

- In the argument during Chapter 3, choose Emily. Ultimately, you don't have to talk to Evelyn at all and you can just ignore her. She will get angry and sign off, but after that Emily will talk to you without a time limit so things will be much less stressful. Make sure to tell Emily to tell Jeff that life goes on after a break up, and that she needs to tell Jeff that they are broken up.

- In Chapter 5, if you have not lied to Emily at all, and you have picked her over Evelyn in the argument, this should work. Click on Matt's profile (matatat7 or something like that), upon doing so you should unlock the Rickroll icon. Equip the icon, go to Rickroll's profile, and there's your achievement. If initally clicking Matt's profile doesn't work, try spamming it a bit. (Pro tip: if you see a little symbol in the top right when you spam Matt's profile, that's an easy way to find his Facenook. It's not important for this achievement, just a neat thing you can do.)

That's it, this is how I got the achievement! Thanks for reading, hope it helped!
