Is it possible to not be sad if you stand in the sun?
If not, then why couldn't he feel any warmth despite being bathed in the sun all day long?
Because of his mother's coercion, his beloved girlfriend left him.
From then on, his world was only black and white.
When he made up his mind not to touch happiness again, she, beautiful and strong, insisted on breaking into his sight.
She smiled and said to him: "You can feel the warmth when you stand under the sun~ Then you won't be sad anymore! That's what I want to bring you!"
When he was willing to believe in the colorful world she created for him, she wanted to leave him.
Will the girl he likes to see her curve up, the girl he loves, the girl who said to her "You won't be sad when you stand under the sun", will she leave him after all?
So, is he really not qualified for the so-called "happiness"?
