Agree. He entered her life as a gay and loved someone she is close to. Then suddenly (maybe not sudden for him but in few months that Sami knows him) he is bi. Tbh I would not take him seriously even he confessed to me. I would probably interpret as he is trying to find himself but not loving me genuinely, rather a whim. And I too , would not consider him romantically.
In Sami's defense and to cope with my second lead syndrome, if my first impression of a person is that they are bisexual/gay, I wouldn't ever be able to see them romantically no matter whatever changes in their sexual identity.
