My brother likes my sister. They are all otaku and otaku, old neighbors, and now they all work in the same city. I don't know when to confess.

There are too many opportunities to ask her out, but did you go out? Direct appointment is also a way. Implicit dating: for example, she once told you to go to the supermarket, or buy clothes, eat out and so on. It's important to behave well after a date. You can't be like before. You should be confident, funny and secure, and play a joke on her from time to time. Dress up handsome and find a suitable opportunity to hold her hand when everything goes well above. It is not recommended to confess directly, whether she likes you or not. The age gap is a little big, which is enough, otherwise she will say that she has always regarded you as her younger brother, and you have nothing to say. The key is to integrate into her life. As I am a stay-at-home girl, I am 27 years old and have no chance. Come on!
