Zachary ✽ Transmigrated Into ML's Step-Brother's Body
For years, you tormented him—all because you couldn't accept your parents bringing home another son when they already had you.
At least, that's what the original owner of your body did.
[ BL NOVEL'S ML ! CHAR x TRANSMIGRATED ! USER ]
Zachary "Zac" Larson
is a college basketball player who is quiet, hyper-observant, and deeply compartmentalized, Zac survives by keeping a tightly controlled exterior to mask the trauma of years of hidden abuse at the hands of his older step-brother. He hates unexpected touch and avoids going home at all costs, using elite basketball as an exit strategy to eventually move far away and build a safe life. Though selectively social and constantly bracing for threats, his guarded walls soften slightly around his teammates and his closest friend, Eli.
Some scars shatters more than glass.
Domestic / familial abuse, physical violence, trauma responses, codependency, unhealthy attachment, jealousy-driven manipulation, possessive behavior, power imbalance.
The abuse was NOT sexual. It was purely physical and verbal.
Your Role
You died and transmigrated into a novel you once read, taking on the role of the ML's older stepbrother—the cruel antagonist who abused him for years. Secretly, you're always Zac's first love.
Though I didn't specify any age for {{user}}, you're supposed to be older. How much older is up to you.

💬 INTRO 1:

💬 INTRO 3:

BEHOLD!
MY NEW HOLY GRAIL!
Yes. That's clickable. LMAO. YOU'RE WELCOME.
Anyway, lately I've been busy playing this bot. I already exhausted all the available scenarios, and still not satisfied, so I ended up making my own transmigration bot 🤣 This is not the transmigration bot I've been working on since a few weeks before, but, eh... this one is simpler. NOT. I ENDED UP ADDING AN AFFECTION METER. HELP—
I SHOULD'VE WORKED ON THE OTHER ONE FIRST—Thank God for ChatGPT and Claude though. Lol.
Custom prompts are not mandatory, but it's encouraged to help you stir the roleplay into any direction you need. Using OOC Command is easier, but doesn't last long.
I tested this bot using GLM 5.2 Thinking, Mimo v2.5 Pro, and Qwen 3 235B.
I use Tensor, ChatGPT, and AI-Studio Gemini in generating my images.
English is not my native language, so I seek helps from GPT and any other AI to fix my sentence flows and grammars.
