Let me just say it's okay to cry (even manly tears) when you watch Sword Art Online. The story is just so heart wrenching; There's a variety of emotions portrayed in this anime: love, pain, determination, betrayal, friendship, unrequited love, kinship, and rivalry. Most people will flag their OTP (one true pairing) as KiritoXAsuna, and I fully support this couple too! They look so cute together.
Kudos to the artist who made this amazing wallpaper!
