Deep love is definitely not a common little love, but a very strong feeling. But it is also likely to be unrequited love or betrayal. (These two emotional foundations are not solid in themselves, and after a long time, there will naturally be unpleasant results. )
Of course, it doesn't rule out that you can't catch each other and shrink back, even if you fall in love and then have simple feelings with other girls. A person's heart can only hold one person at a time, so you naturally don't like it.
