She didn't know why she became evil to Olive. Even though she felt that way, she didn't stop what she was doing. Because what she wanted was to lie to Leo about Olive even though she revealed that Olive was there.
From Leo's face, he looked relieved. While Olive was by his side, staring at him. She tried to show herself to Leo, but she couldn't. Father had locked her efforts like that. Which Olive can only be seen by her fellow humans as well as the angels.
There was pity for Olive, but Aleya tried to act normal because for her, why feel sorry if time can't be turned back?
When the time was so late, Aleya was also reluctant to go home. After a day with Leo and knowing Leo's reaction was unexpected, it was getting harder and harder to leave Leo's apartment.
Leo asked her several times whether she wanted to go home or not. But the answer was always the same: she would be home soon. But in reality, she didn't want to go home.
