The series presents a heartwarming tale of friendship and personal growth. The series follows Taishin, a simple-minded student who develops feelings for Takara, a more complex and guarded individual. While the series showcases Taishin's character development effectively, Takara's character remains somewhat one-dimensional.

The pacing of the series can be uneven. With every episode we witness the character development of Taishin from being simple and easily swayed, to one with a bit of confidence through the support of Takara. Takara on the other hand, is a complex character. He fears his controlling nature thereby distancing himself from relationships albeit being the most popular student who learns to love someone through Taishin’s encouragement.

The series however, fails to capture the potential of Takara’s character. We keep hearing him complain about his ‘getting what he wants’ nature but never see that in action. Instead, we see Taishin stumbling daily around his feelings towards Takara. It gets old and tiresome pretty soon. The series would have benefited greatly in showing Takara manipulating Taishin to love him, only to grow through out the series and genuinely love Taishin. Also, the lack of chemistry between the lead characters is a notable drawback, hindering the emotional connection with the story.

In conclusion, despite these shortcomings, Takara no Vidro offers moments of tenderness and heartwarming interactions. Taishin's unwavering dedication and loyalty to Takara are admirable, and the series provides a glimpse into the challenges of navigating a complex relationship.
