Trying to shoulder the burden all by yourself? Don't be such a stranger. Weep and ask for help. Lean on me with your runny nose. Cry when you feel like crying. Laugh when you feel like laughing. When you're tearing up with an ugly face, I'll give you a good cry with an uglier face. When you're laughing so hard your stomach hurts, I'll laugh in a louder voice. That's how it should be.
I started with this one because I'm literally obsessed with Gintoki and Tsukuyo. They have some of the most "romantic" quotes - well at least, as romantic as they can get in an anime like Gintama.
