IMHO there isn’t anything that can top guildmate next door for me, but:

(Not similar art style since it’s manga, but the concept of being online friends but not knowing they know each other IRL is there)

(Similar artstyle (minus the chibi) and humour, but it’s just strangers to online lovers and meet irl)

(Another gamer online dating one but it’s stranger to online friends to irl lovers)

(Pretty manhwa coloured artstyle, but it’s not gaming related. Instead it’s about hackers, and [KINDA SPOILER] they’re not aware they know with each other irl)

There was also another korean manhwa one with one of the guys he plays overwatch with being in his class and they end up doing a group project together, I forgot the title, but it’s out there somewhere
I'm waiting for Guildmate Next Door updates. Does anyone know a similar story with also kinda same art style? I don't mind if it's GL or straight. I just want it very cute and a bit mysterious, where they're not aware they're friends online and all that sorta stuff.
Kinda cute enemies to lovers, but not too painful for the heart. Because I'm taking a break from toxic stories.
Else: recommend a dark GL story that will have me screaming at 2AM.
