Do you perhaps know the manga Stardust Wink? I was just wondering what happened to Mashiro and Rin (they're just side characters, brother/sister of some of the main characters)? I saw thus side story chapter about their high school days and it did not worked out for tge both of them.

I also saw this one chapter, I don't know if it was in the author's series but Mashiro and Rin saw each other again in their college student days... Please help me find it... Because the ending was sad and they both frowned when they saw each other, eyes full of regret and such...
