You're walking in a greenhouse when you see a small drop of water fall and it makes you yearn for the person you adore. You haven't seen them in so long. But something about being in this greenhouse and seeing that tiny water droplet made your heart burst with longing.
As you yearn for that person from your past, you look back at the drop and see... Bobo (ぼ) the clown?! Uhg. Apparently Bobo dropped that small drop of water.
