I didn’t read the manga but I’m pretty sure it’s just a meme because it’s literally a scene from “Danshi Koukousei no Nichijou” but with Dandadan characters. But even if it somehow is from the manga how is this a giant spoiler with all that kissing and flirting that is going on right now. If they didn’t start dating I’d be very surprised and considered it a giant spoiler but then again I don’t know since I only watched anime.
Yeah, game servers eventually will go down but perhaps steam will still be around in the next 30 years. Right now it’s possible to have a friend that was last online 20 years ago since steam was launched in 2003.
