Wait lang ha, prologue pa lang naman nababasa ko and this is my comment so far.
You’re good with your grammar. A little improvement lang doon ibang part na siguro nalito ka lang sa pagtatype since iba naman iyong nasa una.
Usage of punctuation marks. Eto talaga. Hyphen (-) is used for connecting words and words lang. Dash—em dash dapat ang mga ginamit mo sa pagkoconnect ng clauses.
Lastly, dialogue tag and action tag. I noticed you’re not using it. Aralin mo iyon kasi ganoon talaga sa pagsusulat ng book.
Example for dialogue tag:
“Sue called me,” she said.
Example for action tag:
“Sue called me.” I saw her rolled her eyes.
Ikaw na bahala hahahaha. Babasahin ko talaga mamaya pramis.
