they had a child in the novel thankyou.
But honestly tho... this kind of bl is more interesting than many romance out there... alot of plot and little drama...
On a more serious note... I think people ship male friends in comic because let's be real... in most comics with a male mc... there's little to none other good looking guys close to mc... 90% of people around them are love interests... so I guess people get that feeling of "oh is that a love interest too?". We just got too used to main characters not having true friends at all... only love interests...

There is no BL in this. If there is, then it should be in the Shounen Ai category. Just because they have chemistry doesn’t mean they have to be a couple. They can be friend, it doesn’t feel strange at all ┑(￣Д ￣)┍
