Hmmm, I don't know.
What about.
A boy who repeatedly seeing a dream about a certain girl trying to Jump out from rooftop in what seems to be suicide attempt.
The dream always end right before or when girl jump.
One day the boy meet the girl by chance on the street and the girl was actually new transfer student one grade above him.
And then he will try to get along with the girl to find out any reason that could possibly lead her to suicide.
And spoiler, nothing will really happened.
Because the suicide was already happened.
She is suicide survivor and regret her actions, thus leading her to start a new life.
In the new school.
And what about that dream? Well It's just a dream. Nothing but coincidence. He probably just writing too much novels.
The boy want to be a novelist.
I'm reading a guide to write stories. Here's what I'd do if I understood correctly:
Your description is vague. It seems you want to share something deep about: suicide, regrets, dreams maybe romance. But those elements are disconnected.
If you continue writing, you'll shape your story into something that can articulate those ideas.
You should try to write it for yourself. Just write the events and the general contents of dialogues. Do minimal descriptions about the setting and background.
Think about the set pieces. Those are the coolest climax scenes of the story.
Climaxes I can imagine, the MC wins a writing online competition.
The girls is getting bullied but the MC comes to the rescue.
The MC is getting demolished in a IRL litterature competition and get depressed.
The MC family is having problem.
The girl's suicide motives are exposed. The mc is inspired to write about her story.
The mc finally becomes girl's bf.
His work is ruined by bullies and his grades are rock bottom. He feels he has no future and about to commit suicide.
He gets over it with the power of drugs and hookers(?) I dunno.
As you read the string of climaxes you came up, you'll get an expression of what's in your mind deep inside.
You pick something out of these like:
"having dreams let you achieve great things"
"Having dreams sets irrealistic expectations"
"Life is suffering, holding a dream is only making it more painful"
My joke ending "life is redeemed by hedonism kek"
Pick one of them and hone it. You can remove the events and scenes that were excess. And then squeeze in new events that are thesis and other antithesis of what you chose.
For my joke ending it's really easy to find people destroyed by drugs lol.
Just find what's deep in your mind and hone it. It's hard to do that without writing.
Once you start having something cool. You can tease one of your climaxes in your prologue to reel readers in (maybe)
