Explaining 1st, 2nd, 3rd and 4th povs cause some dont know how to write in those:')
1st person- the reader/the mc/I/Me/My/
2nd person- another character to the mc /they/she/he/(Name)/
3rd person- the narrator/they/she/he/(name/s)
4th person- same as the the narrator but instead of pronouns, it uses you/your/s/you're
Idk hope it helps
