走れぐっちょむ

ぐっちょむは激怒した。必ず、かの邪智暴虐のLINEを除かなければならぬと決意した。ぐっちょむにはサイバーセキュリティがわからぬ。ぐっちょむは、Webフロントエンドのプログラマーである。JavaScriptを書き、ブラウザと遊んで暮して来た。けれども邪悪に対しては、人一倍に敏感であった。きょう未明ぐっちょむは部屋を出発し、近鉄に乗り山越え、30kmはなれた此この大阪の街にやって来た。ぐっちょむには父も、母もいる。女房は無い。三十五の、内気な弟は立派に結婚し実家をた。この弟は、妻と娘の或る律気な営業マンで、近々、業績も伸びていた。新年会も間近かなのである。ぐっちょむは、それゆえ、気まずい空気にならないよう、そこまで遠くない大阪に逃げて来たのだ。先ず、適当に時間を潰し、それから心斎橋の大路をぶらぶら歩いた。ぐっちょむには竹馬の友があった。
