I've also been following this for a long time but there is almost no intention to continue. The story revolves around tea, but the presentation of the tea itself is not appealing. It doesn't have to be a plot, but at least there is something that keeps you stick with the story until the end.
I don't want to be hypocritical, to be honest this also applies to some manga that have a simple premise. But if it leaves an impression, you're comfortable with the characters and etc., it won't be a problem. But this webtoon isn't. It's flat, flat. If the goal is to heal, well, I feel nothing. I think for this multi-chapter format, it is a disadvantage either.
