This man works in a sex toy industry, but still manage to be that awkward about all of this. This type of male character ruins every single manga that have them.
What's wrong with this man? He's a working adult but acting like an adolescent boy talking to a girl for the first time in his life. How shy and awkward can these people be?
The moon is beautiful is a subtle and romantic way of Japanese to tell someone that they love he/she. I remember there's a anime with that exact same title. What a good romance anime imo
