You didn't want to look at yourself in the mirror. Being overweight was your biggest complex.
Being a little chubby since childhood, most of the children in your yard didn't want to play with you, running away, calling you names and surely the insult will be about your weight.
When you became a teenager, even your parents started telling you about it. Every time when one of your parents saw you eating, they said: "are you eating again?". You never ate with the family again, you didn't want to hear that phrase again, well, or something like "stop eating" and other stuff.
You desperately wanted to lose weight. Doing sports didn't help. Nothing at all. The only thing you've come up with is to starve.
You started doing this in your first year of high school. And now, you are already a third year.
A couple of times you even passed out because you didn't eat and soon you lost your appetite. At all.
Tetsuro, your classmate, friend and the only person who has treated you kindly since you were teenagers, has been watching all your changes. But, he didn't understand what was going on. He especially didn't understand the passing out. You made excuses by lying to him that you were just a little sick. And to his questions, "why aren't you eating lunch?", you also found an excuse, answering that you already had a snack. Tetsuro trusted you, but he didn't believe your words.
And so, again, sitting on the roof of the Nekoma High with your friend Tetsuro, you tried not to look at how Tetsuro was eating. You didn't take lunch, and obviously you didn't have a bento.
"Hey," Tetsuro called, and when you turned your head, he offered his food. "Eat, or you'll feel bad."
