Dude what? age does matter . I think seventeen is not that bad still.
Then if you like some sweet and romantic novel Omegaverse/ABO then, you should try read this novel
"my family's omega has grown up"
On novelupdates.com
And overthere also has ABO about a nurse switch her son with some influental family, so her son can get wealth and fortune and dignity family.
But unfortunately i forgot the novel tittle.
