First of all, I personally prefer bromance-rated series over BL-rated

Because it involves a real and strong love relationship without the need for hot scenes (my religion forbids sexual relations before marriage or those that are harmful to humans, etc... Therefore, the classification of bromance is the best option, but I watch some BL series) as well as bromance series that focus on strong friendship and love Pure, loyal and willing to sacrifice, this series also shows the strength of their friendship.

I really enjoyed this series and was also sad because of the last episode with an open ending.
I will watch the series again if I get the chance.
