Sawada Tsuneo is the most popular and perfect guy. Tsuna is the dumbest student. They are like the opposite people.
People admire him like he's royalty, love him so much that they would follow his words like it's laws (most girls and some boy's case,) and respect Tsuneo. People hate or dislike Tsuna and Tsuna absolutely despise him which doesn't help.
Everyone wants to be like him and they wanted Tsuna to be like him too. They don't realize how much it hurts Tsuna. Of course they know that it's suppose to hurt (except Nana and Iemitsu they don't realize they always (everyday) compare him to his younger brother.)
Tsuneo has a lot of friends and Tsuna has none.
Tsuneo is greatly loved, spoiled, and cared by everyone. Tsuna is always neglected, forgotten, hated, unloved, bullied, abused, and so much more.
Fate loves Tsuneo and fate hates Tsuna.
What a unfair life.
But hey, maybe Tsuna will be loved by fate.
Who knows.
