Can’t find title help! (Post WW2 I think)

Hi! I’m trying to find a BL manga I read a while ago and it’s driving me crazy 😭

Here’s what I remember:

  • Setting: post–World War II Japan, during/around the American occupation
  • One main character is an American soldier (or tied to the military)
  • The Japanese MC works at a bar (I think), and that’s where they first meet
  • Their relationship develops while the American is stationed there

Key plot points I remember:

  • The Japanese MC is rejected by his family
  • At the end, he decides to leave Japan with the American
  • They leave by boat to America
  • There’s a really emotional scene where the MC’s mother comes to the docks as the ship is leaving
  • I think they end up living together at the American’s house after

Tone wise it felt more bittersweet/emotional rather than comedic or fluffy.

If this sounds familiar to anyone, please help 😭🙏
