Hi Lavender, as a guy I know the asking out thing can sometimes become more complicated than it should be. As, asking out someone who is not interested can create a lot of tension.
Are you interested in this guy? If you are you can ask him out yourself. Something not too obvious like a lunch or even a coffee. Or otherwise drop hints of things you like to do and places you like to go to, movies you like to see. What you have planned for the next couple of days, hopefully he will pick up on it and ask to join you or something.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
