Translation from your friendly neighborhood weeb:

Title: Dawn (Akari), who's come back to the present day, Volo, who's lived up to the present day, and Cynthia, who's acting like an intimidating boyfriend against a stalker.

Dawn: "Cynthia~! It feels like this guy's been following us for a while"
Dawn (thought bubble): "W-w-why's Volo-san here?!?"
sfx: "Gyuu" (the sound of hugging tightly)

Cynthia: "You got business with my girlfriend?"

Volo: "Huh?"

Part 2 (from the Note) https://pbs.twimg.com/media/FVmexVXUAAAcUv_.jpg :

Dawn: "Girl…friend…?"

Volo: "Is that so*…? How far have you gone?"

Dawn: "Oh no no, in the first place, we aren't even going ou-"

Cynthia: "I've kissed her (while she was sleeping)"

Dawn: "…huh?"

*TL note: Volo actually makes a "Hmmmm?" sound in a rising tone, signaling suspicion/doubt.

Also, yeah, I love this so much ;-; <3
