MTL - My Senpai Knows Magic - Chapter 161 Sacred Letters

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Su Han: No, I want to go into business so I can support you.
