It sounds like you're talking about a scene from a game or app for mobile phones called "How to Raise a Happy NEET APK." In this case, "NEET" usually means someone who is "not in Education, Employment, or Training," and the "APK" extension means it's an Android app package file.
Based on the details you gave, it looks like this app or game has a storyline or gameplay part where players can meet other characters, including one that they can fall in love with. This character is a "slacker" who is willing to work out and has been through hard times in their life. The player's job is to help and hang out with them.
Remember that the things you said about the content, especially the part about a "18+" relationship, could mean that this game has adult or explicit content that isn't appropriate for all viewers. Also, the way connections are shown in these kinds of games should be taken with a critical and responsible eye, and it's important to make sure that the material of these kinds of games follows all the rules and laws in your area.

The Beginning
NEET-chan and I both live in the same room. To become friends with the NEET, you need to talk to her first. You're both happy now that you've taught the NEET about the good things in life.
We spend a lot of time together in the same room. We talk, play with our phones, and talk about life in general during our chats.
Read to your kids and teach them about life. They will help you around the house and at work.
Things are possible when two people live together
You can do anything together, like take a bath, break into the bathroom, or joke around with each other while you sleep.
You can't have sex because you're afraid. This place feels calm and friendly most of the time.
You may need some time to break down your mental walls, so talk to people who can help you.
Adult Study Is Stupid
NEET-chan lives alone and there are no adults nearby. It would be great if you could tell me more.
To "touch" a part, you just have to put your hand on it. Open your heart up and take a good look at it or lick it. You could also use sex toys.
Each frame is shown one at a time with cut-ins in touch movements.
The people who live here are happy with each other.
It would be great if you could show me some new positions and skills and let me know what kind of sex you both like.
On most jobs, you will be able to choose between an objective and an emotional point of view.
You can also choose from a lot of other choices, such as cream pie, rubber ejaculation, bukkake, anal sex, toys, and more.
