The spin-off episode of 'Takara no Vidro' fails to capitalize on its potential. The lack of character development and progression is particularly disappointing. The episode feels like a filler, offering little new to fans of the show.

It was indeed heart-warming to see that Takara and Taishin are still going strong in their relationship but there are still significant things they are unaware about each other. Feels like, although the relationship is strong, there is lack of communication between the main characters. There is no growth or understanding between them.

A potential spin-off theme could have been exploring Takara’s past with his parents and exploring the reasons behind his guarded nature and the events that shaped his personality. Juxtaposing his past experiences with his current relationship with Taishin could create a compelling narrative arc
In conclusion, there is no loss if viewers miss this episode as there is nothing new of offer
