bad font selection, terrible typesetting - you shouldn't use quotation marks in comic works except when required - and it also feels like MTL. and then you got page 50 and 51 swapped, as well as missing page 52 and 61.
Art is 6/10 Story is very close to 10/10. Even though the tyepsetting and such could be better, you very rarely see such wholesome and sweet mom/son doujins!
