[Gomennasai] Toranoana Special Separate Manga Booklet, Wishing You Happiness! [Learn JP with H]

Little Anzu, perched in her apron and sneakers, teases her doting older brother for leaving 'the middle untouched' as he buries himself between her thighs, her breathless giggles echoing off the bathroom tiles. What starts as playful worship quickly spirals into something far more consuming—fevered kisses, tangled limbs, and a brother so drunk on devotion he roars that he'll treasure her his whole life and never hand his sweet Anzu over to anyone. True to its title, the story closes on a classroom chalkboard lesson defining the one word holding it all together: happiness.
