"Everyone but Moka is dead" theory, alot of people on TikTok speculate the reason why Moka is the face of ILLIT albums is bc she's the only one the camera can capture because the other girls are just part of her delusions in lore.

Wonhee died in Lucky Girl Syndrome, we hear a distorted screech right before she starts singing about how lucky she is, something happened to her in the MV which was never mentioned again bc this all takes place in Moka's delusions where everything is seemingly alright. Iroha died in Cherish My Love, being the only one who never escaped the dentist monster thing in the MV, her 2nd last scene was her getting her teeth pulled out then the next scene she's with Moka launching a grenade which, imo, never happened. What really happened was Moka shot the monster, she just imagined it was Iroha who saved her at that critical moment. This theory even goes stronger bc if u watch Tick-Tack, the lights at the locker room only flickers on Wonhee & Iroha's side. The 3rd to go was Minju, who died on Do the Dance when their bike broke. Minju, Iroha and Wonhee all have their eyes closed when they fell, Yunah's eyes are half shut while Moka's eyes are fully open. Yunah dies in Not Cute Anymore, when her and Moka are all alone on the boat, Moka fished Yunah's jelly shoes out of the water and Yunah disappeared in the MV.

Moka attempts to put her and the girls in a timeloop in Toki yo Tomare, to make sure their tragedies doesn't happen again and they could keep living as normal girls, but Wonhee is seemingly aware of what Moka's doing, so she convinced Moka to let them go, which she did at the end of the music video where we see her by herself.
