At the level of the character, the reason is that like all employees of ReLIFE Laboratories An was committed to upholding the rules of the experiment, and it was a job she really wanted to have. Personally An wished that Chizuru and Arata could have kept their memories of each other and even wished that she would not have seen Chizuru's note to herself on her palm, but since she did, it was her duty as an employee of ReLIFE Labs to erase it. This also showed that despite her occasional mischievousness An was not completely irresponsible.

At the level of the story this is related to the major theme ReLIFE has of taking responsibility of your actions, as working effectively and successfully in any social role requires that you do not simply do what you want to do. Every central character faces some sort of challenge related to overcoming their feelings. The two main characters have the toughest time, as not only do they have to work for their present goals, they also have to overcome the problems that caused them to become ReLIFE subjects - which they themselves are unaware of. Arata has to learn to achieve what he wants with hard work, and to regain his faith that he can be a positive influence on the people he gets involved with. Chizuru has to learn to form relationships with other people against the solitary ways she learned in her youth, and to commit to being a part of the community of people around her.

Of the others, Rena has to learn to let go of her stubborn pride, Honoka has to learn independence of what others think about and expect of her, and Kazuomi has to learn to show his vulnerability to the people close to him. Ryō has to learn to allow his feelings to influence his work, and An's flighty and flirtatious behavior is the reason her crush, the more serious and straight-laced Ryō has no romantic interest in her.
