Idk y u think he was romantically attracted to her grandma but I think they had a more best friend vibes and it will make scene. If it were love that was unriqueted and the grandma knew she may not have gone as far as to make a promise it will be uncomfortable. But if it were friendship and they were really close I can understand y she would do something like that

The grandfather is very cute but I don't like how he's projecting his own love for Layla to their grandchildren, like she's gone pops and unifying your grandchildren against their wishes won't be a replacement for your unrequited love.
