Every June 21st or 22nd is the summer solstice.
On the summer solstice, the sun reaches the northernmost point of the earth, almost directly hitting the Tropic of Cancer. From this day forward, the days will become longer and the nights will gradually shorten.
Summer solstice.
When happiness approached me, it was the summer solstice.
The so-called "happiness" means that the person "you love" also "loves you".
