No, I do believe that EXO is close as a whole, some members may be close than others but they are close as a group. They do do a lot of fanservice, especially OTP's such as Baekyeol, a pairing which SM wants to promote a lot but in the end, they do have that friendship and they are close. Some fanservice can be overdone and fans do pick out the fakeness in a lot of fanservice but there are a lot of genuine interactions. EXO obviously knows they're being watched all the time by fans but it doesn't mean that they're creating an illusion 24/7. They do have many, many many genuine interactions that go unnoticed as fanservice is supposed to be something that we're supposed to notice. Taoris crying for each other, XiuChen keeping each other company when the other members are somewhere else, LayHan caring for each other, especially when Lay was really hurt, Baekyeol kidding around with each other, having become close friends in just one day, there are so many ships in EXO, so many friendships in EXO which aren't just an illusion they're hoping to create for us fans. Yes, sometimes they do go overboard with the fanservice, but that's only to make us fans happy, to make us satisfied but overall, they are a group who has a friendship that's not fake. They do have genuine interactions, sometimes I guess, we just need to notice them more clearly.
