I really like the concept and the presentation, however I kept getting stuck and I'm not sure why. At first I couldn't start pong (like, it just wouldn't open no matter how much I clicked on it), then after reloading it wouldn't let me post the second message. This could be a browser issue, so for the sake of testing I tried both Firefox and Edge.

I finally had a chance to replay it and managed to get two of the endings (I'm not sure how to get the first one).
Also, I noticed from the other comments that the response options are limited due to English not being your first language, that's a valid reason, but if you were to update this I'd recommend picking a response word you do know (eg, "fine" for the "how's your day?" question) and using a thesaurus to find a wide variety of synonyms which you could put into an array. If the player has a response that's found in the array, then the game proceeds as normal, and if not then the person you're talking with could act confused for a bit before the game progresses anyway. That way there's no restrictions on what the player can type, and if you miss a few synonyms it's not a big deal.
the only problem with that are the bugs and my stupid self mixing two scripts into one. but i think i could make another script that is filled with functions so that the chat system can call it if all doesnt work.
also for the hinting system, im thinking of the placehpdler text “Say Hello” to change to one of the available words to use.
also im planning to try to add more words that people tried to type in, but then i would be needing to change some of the bot text but thats fine. im happy that you played the game again and enjoyed it a second time!
