This is the final volume in the (fake) marriage to an extremely earnest, elite childhood friend!
"I'm going to fill you up tonight, Haruko."
Haruko enjoyed a girls' night out at a hotel with her friends from college on the weekend.
But late at night, she witnesses her friend Mia meeting with her affair partner.
Haruko can't tamp down her gloominess when Kanade suddenly appears at the hotel and they spend a sweet, unexpected night together!
The two of them deepen their bonds of love, and they finally go from a "fake" marriage to a true married couple...
