Marsha stepped into a room on the 2nd floor which was Alland's private room in the Stanford family mansion. Since Marsha's arrival in the family, the two of them often sleep together in a room that already belongs to Marsha in the mansion. Even the Allands themselves wanted them to be able to stay in the same room for the night. But last night, Alland didn't come home at all. So she wanted to know where the man was now.
Indeed, previously Marsha was in a bad relationship with Alland because that man made Boy annoyed with him, thus making Marsha angry with Alland even though now Marsha no longer feels that anger. However, the relationship between the two of them hasn't been going well because Marsha hasn't met Alland until now. So there is no word of peace between the two.
