The beginning of the series is largely taken up with a bullying plotline that isn't very pleasant to watch, made worse by the implication that the main character's foster brother has not done anything about this for 3 years. The manhwa makes it clear that he didn't know about it, but that's not at all apparent in the series. The story builds up some dramatic tensions that are more or less handwaved away, so once the boys are together there's really nothing left to say, yet the series continues, leading to an underwhelming finale.

So, All wrapped up,
It was a nice little try at the drama. It seems like something someone in school would make or would make for one of those "make in an X amount of time" events. Please no speed running, it needs more story/plot and not to be so rushed. The soundtrack probably needs to be less distracting and choppy. Also absolutely nothing against the actors, Maybe pick actors who are more comfortable with being cast or more experienced with BL? It could make things seem a little less awkward. I'm only saying that because they seemed awkward and stiff during the drama at times.

Overall: it is watchable and sort of cute in a very cringe sort of way, thankfully its a short so one sitting is good enough to watch it.
