Girls who are often hurt in love or feel too tired to get out of the shadows will choose to be single for a while.
However, most girls still need the care of others and the love of the other half.
I don't know if the landlord has met a girl he likes, but that girl is very independent and single now and doesn't want to make friends.
Advise the landlord not to worry. This thing needs running-in.
Get in touch slowly and exert your personal charm.
Impress this kind of girl with true feelings and care about him.
Slowly, they will realize that they still need love to nourish their lives.
I hope it helps you ~
