Honkai: Star Rail: Romance Development System

Su Yunqing transmigrates into the world of Honkai: Star Rail, arriving on the Azure Blue Star as Himeko's younger brother, and activates a Romance Development System.

By having sweet interactions with designated characters, he earns affection points, each of which grants him a heart point and ten years of cultivation.

To ensure he can interact with his designated targets, the beginner gift pack lets him summon a girl of his choice to help him through the early stages.

Unfortunately, he summons Elysia, whose difficulty level is through the roof. Trying to flirt with her is like showing off with a sword before Guan Yu.

Fortunately, he still has his big sister!

Himeko: "Before you board the train and set off, little brother, nobody knows what the future holds. So I want us to go get a marriage certificate."

Su Yunqing: "Huh?"
