an oldie but a goodie- very light hearted and comedic cuz the MC just casually gets together w his classmate out of a misunderstanding. honestly this is top 10 of my fav mangas cuz it's so silly and mmm yum old men muhaha
ppanghouse i luv u- anyway as a queer folk myself this one also holds a nice spot in my heart. it's not old man x old man but hyeonson is the oldie. their dynamic is so sweet so i had to put it here too. -- summary kinda: an old dude struggling with accepting his attraction toward another man after his divorce, learning about how to live life for once
not really old man yaoi until the end/extras, but it's giving vampire and hunter if ur into that. i wouldn't recommend this if ur sensitive to noncon, and the ML gets annoying a little; but he's really sweet to the MC after a while and honestly plus that they timeskipped and are old in the extras i love that
hells yeah- idk if you'd count the ML as old but they are so sweet to each other and i recommend this if u want a short and sweet manga. i like the realism of MC getting spent when they do it cuz he's old, and im all for old guys exploring more of their sexuality when it's later in life; a late bloomer kinda story
