It always been Luhan's habit to come visit Minseok in his family's house since they were both 5 years of age. So, it has been 15 years now. There are no other places that Luhan rather be other than being comfortable in Minseok's cozy bedroom and chatting from morning after breakfast until sunset. At least during weekend. For years, both families always say to them that they cannot be separated because they stick together like glue and they also know each other better than their own parents.
