I`m all for lost contact childhood/old friends AU☝️. Hmmm I have a very little interest in long distance relationship thingy, but strangers to lovers is fine and so about socmed types. I think I`m more fond of classic themes like hanahaki, star tear, related to hanakotoba/florist, sharing-pain in Soulmate AU (or just Soulmates in general), also platonical love. Hanahaki and star tear are both have this `tragically beautiful love story` feel to me. I wish to read more gureshin/shingure fanfiction in those themes and yet i found nothing 😔
