Aww, ang sweet na idea na pareho ang first letter with kuya! Some of my mum friends went with names like Santiago, Samuel, Nathaniel, or Nicolas, classic pero may personality, and super okay ang dating in school tapos when they grow up. If you want something less formal, meron din siyang Salvador, Sergio, or Noel na cute at easy to call. What's kuya's name ba? That might help us suggest something na tunay na magmatch!
