Yui: I'm not suited for cooking after all. Is it about talent? I don't have any talent either
Yukino: The only way to solve a problem is through hard work. Yuigahama-san, you just said "I don't have any talent", right? Rethink that statement. A person who doesn't even put a minimum amount of effort has no right to be jealous of those who have talent. Because people who can't succeed can't imagine the effort a successful person makes, they are unable to succeed.
Yui: But everyone thinks cooking isn't that popular these days. I'm just not cut out for this.
Yukino: Could you please stop trying to fit in with those around you? It's quite unpleasant. Isn't it shameful to blame your own awkwardness, clumsiness and foolishness to other people?
Hachiman's speech in episode 5 resonates with many at 4chan or myanimelist for example. It may hit close to home, but it sums up how a lot of single guys feel regarding their chances.
Hachiman: I hate nice girls. If they so much as say hello, it stays on my mind. If they return my texts, my heart races. The day one calls me, I know I'll look at my call history and grin. But I know that's just them being nice. People who are nice to me are also nice to everyone else. I almost end up forgetting that. If the truth is cruel, then lies must be kind. That's why kindness is a lie. I gave up on always expecting it, always mistaking it, and even hoping for it. Someone who's worked hard at being alone doesn't fall for the same trick twice. I'm a veteran at this. I'm the best there is when it comes to losing. That's why I'll always... hate nice girls.
