It looks like the series of dots that indicate someone is typing a message in chat. It highlights that most the interactions occurred over cell phone and to show that time has passed. The one on page 7 just happened to be the longest pause in the story.
It's fixed now, but at the time of release, the text bubbles in their phone chat had the words in their sentences overlaid on top of each other, making it look like gibberish instead of text.
Ichii-senpai's "So Bold" ... Sugawara-kun (a.k.a. Lucky Bastard) has seriously got to "level up" to match her pace ... and doing so will be TOTALLY WORTH IT!
When she says she's naked in the clubroom and almost 'threatens' that...someone else might walk in?
Of course he'd instantly dash back to the clubroom.
That being said, I think when they started having that kind of relationship it really was only a matter of time before he saw it in the flesh, I'm surprised he was as passive as he was though, I figured he might be the one to request it.
Great ending though. Yeah, don't risk things like that again, just go straight to him and it'll be fine. A sex tape together...? Sounds good, any chance we'll get to see that?
I'll echo that the kerning on some of the cell phone text in some panels is unreadable. Was this done to recreate how it was in the original? If it was, it isn't coming across in the edit, just seems like a typographic error.
Reco <3 (It's been bothering me for a while but whats up with the new edit to make the text almost unreadable? like in page 4 last panel)-Fixed that Also please sex tape chapter next. Please!
