Starting from Their Seventeen Years Old

After transmigrating, Tsushima Kagami finds himself as the adopted son-in-law of the Yukinoshita family, which has recently gone bankrupt. Staring at the graceful beauty in a high school sailor uniform standing before him—Mother Yukinoshita?—he slowly realizes that things are far from simple. The 17-year-old truant, Ijichi Seika: "Things have come to this, so you have to take responsibility! Become my Producer!" The 17-year-old doujin artist, Sawamura Sayuri: "We promised to run a doujin circle together for the rest of our lives, remember?~" The 17-year-old "Part-Time Warrior," Shimizu Nayatake: "Because of you, I’m doing things I can't get enough of." The 17-year-old delinquent, Hiratsuka Shizuka: "We... aren't just 'bros' anymore!" The 17-year-old (crossed out) hot-blooded teacher, Tsukuyomi Komoe: "I cooked for you, I even called you 'Mommy', and now you're going off to find other women?" "In Japan, it is both reasonable and normal for a literary giant to have multiple female companions," the 17-year-old Mother Yukinoshita declared. The girls ceased their bickering and nodded in unison. For the sake of his future livelihood, and for a completely new life filled with fun and meaning, Tsushima Kagami picks up his fountain pen. Starting with a short story titled My Cheesecake-Shaped Poverty, he is forced to embark on the path of a literary legend.
