Obaka na Omega wo Haramasetai

Souta is a brilliant and handsome but disingenuous alpha and is in love with Haruto, his childhood friend. He doesn't want anyone else to have him and wants to start a family with him one day. He lies to his very innocent and gullible friend and sleeps with him every night to mark his territory. But one day, they have a fight because Haruto finds out that Souta has been lying!
