"Hey.. Did you have a great sleep?"
I'm sorry please don't eat/kill/torture me
Nexus Awakened: "Are you ok?", "I'm from Earth too." or, "Hungry?"
Monster Awakened: "I have tasty food."
Facility Awakened: "Please don't turn me into food."
It depends on the protagonist, but one of them is a marshmallow who tries to be friends with everyone. For her, I would just say "hi", and she would take over.
Another protagonist is the opposite of a marshmallow. For her, I would pledge my fealty, and hope I don't end up saying something wrong.
I will sound like captain obvious or the person that destroy the mood in party,
but user R-Envy is probably the best answer
Simply say "Hi" first.
Because if a random stranger walk near you suddenly talk to you, and mention a topic related to you.
Or you are annoyed he is trying to flirt, or he is a stalker. And you will think "Urg, creepy ! WTF"
"Suck my dick."
*Hoping for assisted suicide.
Nota answer is indeed another great answer (if you want to suicide).
I would run, she can straight up traumatized me in some way. My MC is very good at traumatizing people.
Rhaps is the optimal logical solution. [Dont talk to them] especially if protag is not good one.

Another thing.
If you accost the protag with a topic related to them, with their strength and IQ, they will most likely use strength to restrain and force you to confess information. Or find out by talking with you. That you are the writer of his story.
Likely Result is being angry with you about all the troubles he suffered inside the story. Punching you in the face. And control you how to write future story.
Reminds me of the old movie with arnold Schwarzenegger Last Action Hero (1993), the "policeman protag" lost loved ones in the story. Later he even encountered himself (actor version outside) and Arnold (actor) was surprised and tried to hire him as body double because how look alike they are.

Also you (author) are doing a relaxation walk in forest. Protag probably the same. Some people dislike being disturbed when they have relax walk. Also the author's looks/gender can influence ton of stuff. ESPECIALLY yuri protag and you are a man/girl. (clench your cheeks if its a gay lustful op protag and you are a man)
Its better to simply say "hi" or find a common topic to begin conversation. And not hope too much you will get close to them. The higher the hope, the bigger the disappointment when it fails. The lower the expectations, the higher are the happiness if it succeeds.
Because who know how would they react that a nobody acost them.
Its like writing in your story that a random passerby villager without a name suddenly try talking to the protagonist. They probably talk politely but clearly they arent invested/interested and rarely become friends with bottom weak people, nor the readers would be interested in this random boring villager that look like a dog licking fan (chinese slang) that know all the legends of protag.
