Message in SMS? How about a message in a capsule. There are 90 capsules in a bottle, so the only problem is what you want to tell your lover?
Write a secret love note to cure her/him broken heart every meal, every day. Or just like the boy in the movie “Millionaire’s First Love” which is a romantic tear jerker movie, asking her to “eat” it every day to tell her the adore and miss he didn’t say before. Small but potent, a definite cure for sure!
