義理の弟が思春期になった・・。そして、私の全く予測のつかない事が起こった・・。私は甘かった・・。なぜなら・・、これでもう3度目なのだから・・。彼の「気持ち」と「力」はもはや昔の弟ではなくなっていた・・。 My stepbrother is in puberty... And then something completely unpredictable happened... I was sweet... Because this is the third time I've had it... His "feeling" and "power" were no longer his old brother.
