Requiem of the Reborn

Lyra, is your common instructor in a well-known university in Asia and by ‘common’ it does not mean that she is as strict as others would say their instructors are nor she bombards students with noble tasks. Lyra is quite the opposite which makes her popular to her students - she is accommodating, understanding, she knows to sympathize with her students, and she is a genius - in a way that she can teach any subject that you throw at her despite being a major in Political Science. Because of these things, she obtained the title of being the “Angel” of the university.
But despite gaining that title, she never thought that she would actually take it literally not until that fated moment where everything she turned upside down. Who would’ve thought that reincarnation - more specifically repeating your life for countless times is possible?
