Can't believe author used foreshadowing and panel progression for a boob drop.
I'm not even kidding, in a previous chapter, Dragon-girl talk about how her close are kinda tight and her boob's might slip off if it weren't for the buttons.
Then, in this chapter (and the previous one), we see in this order : her only having one button set (since sha was in a casual situation and didn't want to be too tide up), then said button popping off, then her tits slightly getting out, before finally setting free.
ALL OF THAT, just for some tits the we've already seen.
This manga I'd either the best or the worst, no in-between.
