You could fall in 'love'. You could fall in 'like'.
'Like' is something clear. You will know it when you like something. You can think of why or how you like it. You can adore it and feel like wanting to have it.
'Love' is something which is not clear. You are not aware of it. You don't know how to describe it. Sometimes you avoid thinking about it. You may deny it. You feel something which you don't know about. And it makes your day brighter. Happier. You smile a lot and you don't know what is actually happening when you are with the person.
When you are not with the person, you think about that person a lot. -That's love.
