I know, that's why it's nice.
I also liked that we actually got to see the kiss itself (even some yuri manga has the camera pan away from kisses, which is weird), but without making it weird by zooming in or something.
Pleas read it from the beginning, it may hurt but it will make build up relation between you and tomoko. Watching tomoko suffering from her social anxiety untill growing up and "accidentally" attract other weirdo + become little bit more popular. All of it, will feel more satisfying if you read manga from ch 01. Trust me!
Specifically, the outfits are from that episode where they were investigating the White Fang and ended up taking on Roman in a stolen Paladin mech. I wish they wore those outfits more often.
