This is dedicated directly toward getting to level 3 since there's quite a bit to it. Though I would like to quickly note this dialogue when talking to Valerie in bed. "You are not the useless boy I thought, or at least you changed." A simple change: "You are not the useless boy I knew, you've changed." Would probably hit harder given what she's said and done from the prologue leading to this.
Anyways, once you sleep and talk to each of the girls respectively, you will break up with Zoe through a dream of all things. Depending on how you go about this, you will have to choose between 4 of the girls.
Berry: Pick up the package and help her with it. After heading to her room, POG champ peeks in and plot. "The beast will come to you" the best way to sum up her lust toward you if I'm honest. Let the night pass and she will get you herself. I also found another error. During the time Berry has you in her grasp she talks to you about having a girlfriend. This line is brought up after mentioning "Including making you happy." Line: "Why are you talking about another girlfriend" should be said by the protagonist. So when she eventually straps you down one of 2 reactions will occur: If she is taking your V-Card she will be one happy beast of a woman. If it is anyone else she will have a different reaction.
Sarena. At night she awaits to hear the good news in the backyard. You will have to wait until you get some sleep to progress. After that, make one new video which will make you two, officially a couple of idiots. And simply wait until she calls. That is it. A "stream" will happen. If she is your first (as was my case), she will take pride in having taken your card. Now, before this happens your relationship to the other girls (If they are at level 1 or 2 for example) your thoughts will change slightly. Nothing too significant but he'll acknowledge that you haven't finished their respective quests. He will also mention those he have done with it before if she wasn't your first.
Valerie. She will be chatting with your Dad at night. After that, witness her show and after the night passes you get a call. Talk to her in the backyard and she will give you a massage after giving her a compliment. It won't happen unless it is on your terms, which apparently is to humiliate your terrible excuse of a Dad (just get the night to pass and it'll happen).
Emma. After peeking on her, she will be in Valerie's room having a chat in the evening. I have detected an error in the script. Valerie should be saying "Why not" not Emma when she asks Valerie if she's sure Ero will like her being gentle. Anyways, BACK TO THE STUFF. You continue further after sleeping and eventually you inform her what Chad had done. Once finished, she will approach you at night with a very important question: "Do you love me?". This has two responses and no real effect for 0.3.0.1 thus far. You either confess your feelings toward her or you don't. This won't lock you out of any content seen after. Though there are dialogue differences when doing it (regardless of if you have already committed to someone else before). But that won't change how you interact with the rest of the girls once they're at level 3 as well.
