What's your "Came for the X, stayed for the Y"?

[Slappy Bird 108]

What example of your own "Came for the X, stayed for the Y"?

Can be anything from media, products, location, activities, ect. You don't have to reply it as "Came for the X, stayed for the Y", it can be more detailed.

 

For me: I discovered this visual novel called Haru e to Tsuzuku Oka, and I only know about it because of my favourite music artist, Mamomo, composed music for it, but the story is interesting enough for me thanks to using Google Translate.

I came for Mamomo, stayed for the interesting story

Another one: There's an MLP fanfic series called The Hero of Equestria, that retells the story with an audience surrogate OC. He has a harem with the Mane 6, but the actual story (both the romance and adventure/slice-of-life), and pop culture references was enough for me to keep reading it since middle school.

I came for the harem, stayed for the story and funny reference.

MLP makes for a good example, came for the show (FIM) and stayed for the awesome fandom, people, events, art and music, all so good how could I not stick around?

For me there is also Warhammer, came for tanks, stayed for awesome lore

Equestria at War. Came for the gameplay of the mod, stayed for the amazing writing and characters. Now one of the characters is a permanent part of my personality (Posada).
