Vital energy deployed by lothario — might he ask for your hand? (11)

'he ask for your hand?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'vital energy deployed by lothario' is the wordplay.
'vital energy' becomes 'chi' (term for life force in Chinese philosophy).
'deployed by' means one lot of letters go next to another.
'lothario' becomes 'romancer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chi'+'romancer'='CHIROMANCER'

'might' acts as a link.
