Help please

Im looking for two yaoi mangas. One is where the seme knows about computers and his childhood friend comes over to learn. They spot the toy the seme has and proposes that they will model them for his research.
The second is where the seme tells uke his dog died cause uke fed him something bad and that the uke has to be his dog. The uke gets attacked by bullies and the seme finds them and offers himself instead.
Thanks for the help.
