Few things:
Either those two are so in love with each other that they have blinds on their eyes like horses do, and cant see any part of the world beside each other, or the reaction faces of the "stan-squad" are exaggerated like 100 times for comedic purposes, cause my god you would need to be blind or oblivious totally to not see people with faces like the trio had when the MCs welcomed each other.
If they marry and invite all the fans/stans/people who witnessed their blooming love, they would need to fucking get married at some Olympic size stadium/venue with like 50k chairs at minimum
Also the trio needs to invite 4th person - a hacker - so that they could hack and read the couple messages for full view - like they watch their train interactions
