The only way to convey ur love is a good confession .
And u have to time ur confession right.dont do it too early.
Do it early and it would be a guaranteed no ..... Do it later and u will be friendzoned
U shall know and you'll be pretty confident that ur crush also likes u.
Look for those little signs .
Stand by her in her problems.
Make her laugh.
Show her that when there would be no one by her side ......you will be there .
Peace man
