Love is an illusion shows one of the main characters with a pregnant belly
Ummm are they like sad or like those yaoi that makes you cry
I want to read thm but im kind of scared.. :)
You can say that it's a little sad (the backstory that is) but the couples stay together and in love and it has a happy ending. You should definitely read it, it is one of my favourite mangas!
It'll make you cry but in a good way(▰˘◡˘▰)
NIIICCCCEUUU THANK YOUUUUU
OMGGG IM SO EXCITED NOW
OKKK... *hyperventilating* yiieeeeee
It's a really beautiful story of two couples who have some difficult background, but their love stories are beautiful and the relationship between the two couples is beautiful.
In all my years of reading mpreg this is the first time I've seen an actual physical pregnant belly on the MC like woah I'm floored (≧∀≦) http://www.mangago.zone/read-manga/unmei_no_kisu_wa_oazuke/mi/49b4aa8ce88be6bfafbbf3cbf92b7592_chapter-5/15/
