I suddenly got my past life memory back, what to do (asking for a friend...)?

*Real synopsis: Alean Steelight, son of Baron Steelight, 4th generation of frontier knights, is somehow a mage? And mages can only be supports? In the frontier where dangerous beasts and monsters stalk the land, mages who can't pull their own weight in combat are considered trash. After being dumped by his parents at the Royal Academy, Allean must somehow survive the most heinous place known to mankind, high school. Now if only he didn't suddenly remember that this world is going to end, it would have been much easier on his mind at least.

=====================================================
*Disclaimer: This is my 1st novel, and English is my 2nd language, so expect some spelling or grammar mistakes. Also plot holes, and generally bad planning and such. Feel free to point out mistakes so I can grow as a writer. Update whenever I have time and inspiration.

If you think the name is familiar, I do take inspiration from " The world of Otome Games is Tough for Mobs" and other academy-type novels.

*Warning: This novel features references to self-harm, depression, suicide, etc. Viewer discretion is advised

If you are uncomfortable with LGBT+ elements in a story in any way, then this novel might not be for you, sorry.

The main character is straight/bi-curious, so yeah... Yay teenage hormones and confusion.
