First of all, how dare you!!
This was the worst possible ending, you didn't even give them proper closure.. Didn't give the old man a chance to redeem himself, to say he's sorry, to vocal his reasons.
It's like u threw him out of the window making him the villian to the innocent young boy and then showing us how the boy's struggling not to be like him after getting scarred.
Tbh you could have made a normal ending when each of them go their separate way, not all love stories end up in a happy ending yeah, but this was beyond rushed and hella unsatisfying..
Tarou-san is so cute and a big softiiie!! I wanna see more of him ugh my hearto fell for him.. Hope he gets along with the rabid dogs (๑•ㅂ•)و✧
