A quick, fun and entertaining read of two best friends finally admitting they have feelings for each other.

I found it a little frustrating that a lot of the humour was portrayed in a negative grumpy way from the MC - he hated this and hated that, when he clearly didn't and eventually it got a little tiresome.
However, overall a cute story that had me smiling. Also a refreshing change to be reading a story set in Nigeria.

This was my first book by this author and I enjoyed the story! We have all probably done or said things such as, "if this doesn't happen by....then I will do this" well imagine it's "I we are not married by 30 we will get married" no big right? Ha! Wrong. What if one of you is gay and the other straight? What happens then? How do you move from friends to lovers, without ruining your friendship?

Creative book. I enjoyed the characters and the world building. Will be looking for more from this author - 3 stars

When it comes to LGBT+ fiction, I really love the whole friends to lovers trope. When Did 30 Become A Big Deal? is a short novel that focuses on just that. Sanmi has just turned thirty and his best friend for 20 years, Bidemi, reminds him of the pact they made as kids. If neither of them were married by age 30, they would marry each other. Sanmi assumes Bidemi is messing with him, since he's never got the inkling that Bidemi is gay. But Bidemi is completely serious and he's willing to do whatever it takes to make sure that Sanmi sees him in a new light.

One of the things that I LOVED about this book is that it's set in Nigeria, so being out and open about homosexuality isn't safe. It's also exciting to read a book set in a different country, especially one I don't think I've ever read about. Sanmi and Bidemi are great friends and it was fun seeing the two of them grow closer in a new way. This isn't a gay-for-you novel, though I don't always mind those, in case you are worried about that particular trope.

There were a variety of side characters that really added to the story, like Sanmi's other best friend from work and both of the boy's parents. All of them are pretty supportive about Sanmi's sexuality and they don't seem to mind the idea of Sanmi settling down with his best friend.

This was a short and sweet novel, with some added humor, which is always a plus!
