ugh i can already predict it. the manager is gonna leave hes gonna be all "we cant be together because long distance relationships blah blah" and she ends up with black hair guy OR they stay together and then shes gonna feel lonely and she gonna end up with black hair guy. UGH the manager is way too nice tho i wish she can stay with him!!! ╥﹏╥

welp if we look at it at an analytical perspective the black haired dude is still being shown on how much he miss's the mc and how much spotlight he has in the actual manga. Now if he wasnt being shown then that option would be reasonable but even so we all know there will be a third guy who interferes. It's cliche but gives the story some sort of movement and body where as if we take account of the option you offered that is waayy "to cliche" giving each character no "drama" making it a dead story. Sure you can do a lot with just "oh we will be faithful and wait" but its really hard to do it because most of the time you want to see character development as opposed to a time skip and then the end.
where can i find more yaoi like this?
U mean the smut? Age gap? Or story line?
All of them (๑•ㅂ•)و✧
