man i love that you noticed the details!!! anyways, you actually got the true ending, to get the good ending by engaging him in conversation about his favorite movies then being flirty with him. The secret ending I answered below this comment on how it hehe
-SPOILERS BELOW-
Oh... then I've definitely gotten those. The endings I've gotten, in order;
1. Inf3rn0 insists he did this for me, and Admin hacks me into a good ending.
2. I flirt with him and after slamming down my phone, realise I have his lighter in my hand.
3. The Secret ending where the Admin has the audacity to use my actual, in computer name.
Does that mean the secret ending is the third ending?
Aaaah, I see. I was being too accommodating when we met in person. Thanks for walking me through the last ending! Aaaah, I'm so excited to see how the rest of this game pans out!
...and what other, original YanChat references we may see. I wonder how these remake characters would respond to some of those old asks?
