I was really pleasantly surprised by this BL series. I suppose the main reason is the originality of the plot. Everything starts with a certain focus on some friends trying to develop a vlog channel, when a "newcomer" enters the scene. Then slowly our attention shifts on the new relationships develop, and equally importantly, on how these ones affect the old ones. When secrets slowly get revealed, the plot thickens. What I really liked about this particular aspect, is that the secrets themselves, although they trigger changes, it is not their revelation per se but rather their effects on which the story concentrates.
The acting is quite good. Perhaps not stellar, but then again it is not needed. This is one of the rare cases in such series, that the emotions of the characters are adequately described by their actions, and therefore overly emotional outbursts are not really necessary (which does not mean that the characters are blunt, it is simply that the series does not rely exclusively on the chemistry between couples). I also liked the side couple's story, which beyond filling air time also supports the plot (having been an established couple for four years). All characters are mature (in the sense that they adults and use their heads, but also grow as time passes by. Perhaps they are all a little bit too good-hearted, but then again this does not save them from pain (which for a change does not stem from a crooked world or a particular big bad wolf).
Perhaps some viewers will be perplexed about the existence or not the temple our adventurers are looking for, but in my opinion this is completely irrelevant. The quest more than adequately serves its purpose in offering material for the vlogs - it gives the backbone but not the flesh and blood to the plot. It is nice to occasionally have a story which is different, in that it makes you think a little bit, and not just brainlessly cry your eyes out.
Compared to the overall rating of the series, I give it a relatively low rating for the rewatch value. This is no contradiction, it is simply a consequence of the genre. It is neither a comedy, where one wants to listen to funny lines again and again, nor a sweet romance, where one simply wants to enjoy passion. Here we are dealing mainly with realizations, which per definition are absent in any subsequent second run.
