The two fell in love one night and then rented together. One didn't want his life to change because of love and refused to fall in love, and the other was too busy with his career to have time for love, so they got together.
The two people who live together like this are so stubborn that they can't be together. They are so ruthless when they get out of bed and intentional when they get into bed.
Intention: the gradual process from feeling in love in one day to feeling in love over time
