I've Reincarnated as a Nameless Side Character: Becoming an Alchemist to Avoid My Demise, Chapter 16

One day, Grete von Lilienthal realizes that she has been reincarnated as a character of the romance simulation game she was into in her past life. However, she is not the heroine or the villainess, but a nameless side character! All seems fine and well until she realizes that if she continues with things as they are, she will get caught up in a fire at her academy and die! Now, to avoid the death flag, Grete decides to change her major to magical medicine, which hasn't had any applicants in years, so she can avoid the main building where the fire will happen. With the course of events now taking a turn away from what she knows, an incredibly handsome elite scholar is now her teacher. Furthermore, the heroine and the villainess keep trying to get together with her to talk and become friends! All she wanted was to quietly survive the events of the game, but somehow she's now the center of attention?!
