Perhaps the Kelly/Seamus relationship is being replayed as Shamus/Matt. We don’t know how Kelly and Seamus met but at 19 fairly sure Seamus did not have much compared to Kelly having a car dealership plus other business interest and coming from a family with money. Matt feels that he has nothing to offer compared to Seamus. Hopefully Seamus will draw from his relationship with Kelly to help Matt understand and feel more comfortable.
regardless, loving the story and looking forward to the next chapter.
Thanks for all the work you put into writing stories - greatly appreciated.
