Spoilerish but based on the novel (no English translation & raw I know of except for the official) this is a simple, straightforward, fluff, lighthearted story with sprinkles of hacking stuff here & there just to add some spice & thrills. But basically ML sweet words is not a joke lmaoo, he is just a corny & flirty man like this when it comes to MC probably because
Spoiler!
He is VX & he really missed MC during his disappearance & he's afraid the MC will run away again for good in real world too.. Anyway may give some other spoilers next chapter if I remember idk lol.
@Lilac but the problem is, he knows cuz he feels it, we know cuz we are the omnipotent reader, but our MC does not
TO OUR MC HE JUST MET A MAN, Who suddenly impose on his life, stalkerishly stand outside his home at a time when MC randomly decided to leave the house, has no regard for personal space, and says CREEPY STUFF
