Help me find these two manhwas please..TT

One manhwa has an uke with blueish green or something like that hair color and the seme has white hair. The uke and semes mother were best friends and so are their sons and when they start to grow up, the uke seems to think that the seme hates him but then figures out that he likes him back TT also green flag seme
The second manhwa also has a white haired seme and is a college student (?) and the uke has black hair and is a bit more darker than the seme, they are also childhood friends and they kissed one time in their childhood - -
