Greetings!

I took the liberty (because why not?) to try and achievement hunt to 100% in Sakura Sadist.

Anyway, I'm gonna continue with the routes I took in order to get achievements.

1. Pinch them.
2. Tell Marilyn you're getting up.
3. Lick that hand! You know you want to!
4. If you keep looking this adorable, you'll steal my heart!
5. Tell her you think maids are cute!
6. I was looking for something I dropped.
7. Let's not antagonize her any further.
8. ...me!
9. Because you're smarter than me!
10. I have no idea, sir!
11. Let Mari sip her own tea.
12. Act like a brat.
13. If you ever have the time, I'd love your help!
14. Your favorite color is red!
15. Tell Mari a white lie.
16. Tell a lie.
17. Change the subject.
18. No way! I'd never kiss Mari!

6. I'm just enjoying the view
7. Say it!
8. ...you!
9. Because I like you!
10. My sexy body?!
