The first assumption you may make about this series is:

'The characters are playing beach volleyball in swimsuits, this must be a shallow series overflowing with cheap fanservice!'

Your expectations will be shattered by this heart-warming story about two very different individuals helping each other to overcome their difficulties, coupled with a great soundtrack - which just happens to be set in an environment surrounding beach volleyball.

Thus, I can only imagine a not insignificant amount of negative or mundanely average ratings are are left by people who had misled expectations of what they were getting into, and entered the series without the correct mindset - that is, to have fun!

While the story may not be as engaging as a mystery series, nor as action-packed as a shounen, the unique twists of reality brought into the plotline help the viewer to genuinely connect with the feeling and characters of the story. Many other series I have seen have been too predictable and ultimately boring due to overdoing 'feel-good' clichés in the story to meet fan expectations. However, this series manages to balance the fun element with a little drama to enhance the viewer's enjoyment, rather than doubling down on these overused clichés. Nevertheless, the plotlines of these types of story are never the greatest; yet this may be a required element to obtain the atmosphere of the relaxed, 'feel-good' genre.

The colourful, clean art style of this series is a strong point, fitting the atmosphere this series creates with its storytelling and environment perfectly. Although the character art is not the most detailed or complex, I think this simpler art style was the correct route to fit with the direction of the story, and the detail in the backgrounds more than makes up for this. The colours are what differentiates this art style; with hard and soft lighting effects, and even shadows being used to add colour and atmosphere to the scenes. The art avoids becoming too childlike by using pastel colours, with a subdued use of the bright, primary colours.

Finally, the greatest asset to creating atmosphere in any great video-media is sound, and this series is no different. It only takes a few seconds to realise how great the soundtrack is, and a few more to be drawn into the fun feeling of this series. The immersive soundtrack flows with the storytelling, oscillating between exciting and heartfelt moments like waves on the ocean; so just turn up the volume, relax, and have a great time watching this series!
