Osananajimi-tachi ga Ninki Idol ni Natta: Amaama na Kanojo-tachi wa Ore ni Mitsuide Kureteiru

Kazuma Kuzuhara, a high school student who doesn't want to work, spent his days mooching off the huge amounts of money lavished on him by his childhood friends, the idols Yukina and Arisa. However, their excessive love of the two gradually begins to border on madness...? A dark youth love-comedy about living off the generosity of others!
