[Gameplay]
Manipulate the two character's feelings by deciding their hour-to-hour schedules.
Show them all kinds of videos or release gas on them.
Setting the same schedule can lead to different actions depending on their feelings at the time.
If their feelings of love or sexual excitement are high, it might lead to sex acts.
After your scheduled activity is finished, the two of them will act freely for the next hour.
During this time, the tentacle will actively pursue the girl.
Depending on their feelings, a range of play may occur.
If the girl becomes aroused but doesn't like the tentacle, she will masturbate in a variety of ways.
At the end of each day, depending on the characters' stats, a number of events may take place in the bedroom.
