It's honestly not that common to see yuri that slowly build up nowadays.
Most of the times Romance/Big guns hinted right on 1st-2nd chapter.
Meanwhile the author went for the slow build up kind of story.
The only time I hint of romance is on 3rd chapter where Jun is "Close to confessing" to Saki.
Would be a nice if it's serialised though, more pages! (and probably more works)
For anyone wondering, on p3, Jun's noises are just doki doki doki, and at the bottom Senpai's just like "mendokusai" x 3, being like meeh what a pain/too much trouble
On p5, Jun's gasp sounds like, "Huh?!", to me
