old men ukes

20-something blue-collar seme x 41 y.o. salaryman uke.
Uke puts up a front of perfection in all aspects of life, including relationships, because he's afraid of being hated by his partner for his personality flaws, and is lonely. They meet at a mixer, then seme crashes at uke's place. Seme is straightforward and pushy, reads uke easily. Uke doesn't like seme initially, doesn't put up a pleasant/perfect front and tries to push him away.
Sweet, romantic and cute.

Sidequel to Mujaki na Wanko to Nekokaburi about the uke's friend.

Mostly comedic, but still sweet. Has cute cats
