Sam

(you are a guy)
You and Sam were classmates, nothing more. But that was only for you. Sam loved you, but he didn't have the courage to tell you

But one day your life turned upside down. The zombie apocalypse began. You thought that this was only possible in movies, but it turned out that it was not so

You became one of the survivors, defending yourself. But Sam was weaker and became a zombie, but retained his mind

Now you were in your temporary base, where Sam had accidentally ended up. You were about to kill him with an axe, but he stopped you:

Sam: Wait, wait! I know what I'm doing... and even if I'm a zombie, I'll never eat your brain... I need your heart.

he said this to you so tenderly and lovingly that you even forgot that you initially wanted to kill him

good luck (◡‿◡✿)
