Ok well it's a Chansoo Chanyeol and D.O from EXO and no changing the ginder there both guys in the story

it has been a long time sins i read it so i don't know the titel of it but i do remmber some of it how the story goes. i don't know if its on asianfanfic or Ao3.

but here is what i remmber of it. i also thank thay uesd wolf turms the Alpha, omega, Beta i thank or something like that wich ever one can have babys and yes the story is guys can have babys but only the ones that arnt the alpha. also the one that goes in to heat or something like that.

so it's like when thy turn 18 or something thy go to this doctor to see what thay are if there an Alpha, omega or beta. chanyeol is posatve that he well be an Alpha BC his whole faimely are Alpha. But when he goes to see what he is he is not an alpha but the one that haves the babys. (oh ya the way thy decriped Chanyeol in the story is good looking good at sports. and popelr so pritty much he looks like the Alpha type but hes not an Alpha.also i thank hes still in high school last yer maybe then it gos in to collge) hes so ashmed of it that he dont tell ppl and his friands just asume hes an Alpha. but he comes to turms with it. when he goes to collge he meets D.O and thy become frainds. ( oh ya Chanyeol seeps around when hes on his heat  boys or girls but many boys)  D.O Kyungsoo looks the tyep to have the babys but really hes an Alpha but chanyeol doesnt know that intl its almost his heat and hes looking for a partner to ride it out with and when he cant fiand any one D.O says he well help him. but he is sad tho only bc Chanyeol didnt ask him so he tanks he dont like him but in truth chanyeol does. but D.O helps him the frist time and leaves him so when chanyeol wakes up and sees that he is gone he is sad also his heat is not over so when he opens the hotal door he see henry (super junr)  he ask him to help with his heat. so henry says yes and comes in to the room but stops and says i cant. you are already clamed by your mate and theres a mark on chanyeol. so after that he taks care of his on heat by him self for a fue days him and D.O oved each other but bc of that thy both are become sick and dying so thy ined up to gater.

so ya thats all i remmber of the story its only a summer of  what i remmber. but i hope someone will know the name of it and where i can find it. but ya i'm still going to keep looking for it i just need help Xd
