I love it but

Considering the flash back I’m afraid to say that is not the case... the seme has to be at LEAST 15 to drive a motorcycle, add some years to that for being a gangster with the mom BEFORE having the uke... so I’m guessing the age gap is at MINIMUM 20-25 years

Well from what I gathered, seme is same age as mom (38) and uke is starting in university (so around 19). So I'm guessing we have a 19 year age gap. Which is not a number you want especially if he even took care of him as a child. ╮(￣▽￣)╭
