Give it to my dear one,
May you go through thousands of sailings and come back still a young man.

Things to note:
①. The heroine is a Mary Sue, not an ordinary Sue. If you can't accept Mary Sue, please don't get involved.
②. It involves TM, but it doesn't really matter (after all, this is just a story about love)
③. The male protagonist is very obvious
④. That beautiful girl Airi Akiba with eight-pack abs under the appearance of a CEO (no)
⑤. Although it is a Conan fan, there is not much reasoning and it is even directly copied from the original plot (.
