butthole's Questions (2)

im trying to find this manga, but I forgot the name. the MC was reincarnated and was raised by 3 heroes. expect the heroes were undead. the grandpa was a ghost, the dad was a skeleton, and I forget what the mom was, but she used to be a priest so she would pray to her god for bread for the MC and would be set on fire because of it. The MC gets burns on his hands from trying to save her from the fire (when he didn't know what is was). Does anyone have the name?

So, i've been trying to find this BL i read here a while ago. I forgot the name but it was two scientists/reaserchers. The top had lighter hair (I think) and had a really sensitive nose, but he thought the bottom smelled good so he sorta developed a smell fetish for him. Also, there was this one scene where the top convinced the bottom to give him his underwear and that's hot the kind of came out to their research team. I think they were in college and the bottom was older and had been sabotaged by his partner before so he had trust issues and had to sip a year. Does anyone know the name?
