Sometimes I don't understand why the protagonist doesn't just speak up, like yell at them STATING they were the cowards that treasured their own petty little lives more than saving the life of the Chieftain, and that the older brother Ryu is a selfish, entitled asshole that thinks the world is ALL his for the taking just because ONE individual decided it wasn't worth it to fight him, and the mother... Okay I can't actually say much about the mother dragon, it was effectively stated that only one dragon should hatch from a twin egg, and survival of the fittest I guess, so the second baby is abandoned in hopes that she can focus all her efforts on one child. She's still a bitch, don't get me wrong, but I can't REALLY fault her... (Flashback to BBC Earth's Dark Side of the Shoebill.)
That whole rant aside, I know why protagonists don't say the thoughts that goes on in their heads. Because it doesn't do jack shit. The opposition doesn't care what you think, they just want everything to go their way. If what you say makes them feel bad, the story demands that they completely ignore whatever MC says and continue to tear them down regardless. Case in point, most recent chapter of A Breakthrough Brought by Forbidden Master and Disciple.
No closing thoughts. I still really like this manga. Just a small gripe I have with the ending. Sorta.
