Net Girlfriend! ~A Sweet Cohabitation Life with My Shut-In Girlfriend~

Reina’s parents had to be away from home for a while due to work, so she came to stay at the protagonist Hiroki’s house for some time. Since their parents were close, and Hiroki had a responsible older sister, Natsumi, Reina was welcomed warmly.
Although Reina and Hiroki were childhood friends and had played together often since they were little, this was the first time they were living together, so Hiroki was nervous. Reina was quiet and didn’t show her emotions, so their days together were somewhat awkward.
Through the accumulation of these ordinary daily experiences—eating meals together, playing games, studying—Hiroki began to notice new sides of Reina…

A crazy life of cohabitation with the goddess Mel in a one-room (stable) room!
There’s laughter, tears, touching, and sex! What on earth will happen?!

​​Your girlfriend (whose name can also be changed) is a slightly flashy but very cheerful childhood friend.
She doesn’t even care if her panties are showing, and she’s popular in many ways at your school, which has few girls!
At first, you hated the idea of ​​her being everyone’s fantasy.
However, you gradually realize that even though you hate it, you’re also getting excited…?

That day, after that stream ended──
With the support of a mysterious sponsor, an older sister and a younger brother, now a university student, are freed from financial hardship.
They were finally supposed to be able to return to a "normal life."
But one day, an "intimacy gauge" suddenly appeared above their heads.
It was a sure sign that their relationship was no longer "normal."
They cook dinner side by side in the morning, and cuddle on the sofa watching movies in the evening.
Their fingertips touch in a spontaneous gesture.
Before they knew it, their time alone together was getting longer and longer.
The "fictional love" they acted out in front of the stream camera quietly and surely transforms into "true feelings" in their everyday lives away from the camera──
 
Until the day they cross that forbidden line. These brother and sister's tender, little by little, passionate "romance sim" life begins now.

You awoke in a small, snowbound guesthouse.
You were stranded in a blizzard and will be staying there for a while.
There’s the cheerful older sister, Sonia, and the quiet, intelligent younger sister, Iris.
In the silent, snow-covered mountains, a warm life together with the sisters begins…
