ch 1-2, 6 for the story with the useless uke x yandere seme. Seme isnt a dangerous yandere but he does become obsessed and creepy for the uke. Uke doesnt mind it and thinks its cute :) Uke relies a lot on the seme bc he is pretty useless. Seme feeds him, clothes him, houses him, and also relieves him (progressed to jerjer in the story)
