The 3rd numbered title produced to commemorate the 5th anniversary of the graduation series in the game world that springs to mind when it was released in 1994 . Like the previous work and the previous work , it is a training simulation game where you become a teacher at Tsinghua Girls' High School and help the students to graduate safely. In this work, the main character is married to one of the heroines selected at the beginning of the game, and is set to live under one roof.

The game period is from April 10, 1998 to March 8 of the following year. Enter the weekday class schedule in units of one week, and go out with your wife to a place selected from several date spots *1 on holidays. School events such as school festivals, seaside schools, and sports festivals are played with mini games.
In addition to the conventional training simulation, an element of ``hiding the secret of being married to one of the students'' has been added.
When a student in charge of a holiday date with his wife witnesses him, rumors arise within the school about the main character and the student who is his wife. It wouldn't be a big deal if the student who witnessed it was quickly silenced, but if this was left unchecked, the content of the rumor would escalate and spread far and wide. If the content of the rumor reaches the stage that "the main character is married to the student", or if the rumor spreads to a certain extent regardless of the content, the fact of marriage will be scooped in the school newspaper and the game will be over.
General girls other than the five heroines will appear only in the event CG displayed at this time. By the way, Asuka Hoshino, who appears in " Sentimental Graffiti ", also appears.
Also, if you don't care about your wife too much and hurt her mood too much, you may get a bad ending of divorce.
Although it has a CG recollection mode, not all event CGs can be seen, and holiday events (holiday dates) and family events (events such as birthdays and Christmas) are combined.
