Hey there, i'm your new reader..
As you said in your note that you wouldn't mind some suggestions about your work.. I would like to help you with kinda polishing your story.
Although the story, characters and plot is well designed i think you should edit a bit of writing style.
To make your writing more effective and pretty. Use commas when you add multiple things in just one sentence , break the big paragraphs and add space in them so it doesn't make the reader annoyed , and yeah make sure you leave author note in a way you aren't shown like a beginner (write author note short and just bubbly. Greet readers or just give a reaction on chapter. To engage readers , you can even have a short question so you can convey with them)
Yeah thats all.. Hoping this wouldn't annoy you. I don't really read hetero couple story but i love this storyline now.
