Yunho posted congratulating BoA on her 18th anniversary (debut on 25/08/2000)! Both of Tohoshinki and BoA performed at the 2018 a-nation Tokyo performance’s first day (on 8/25) at Ajinomoto Stadium, and the photo seems to be of her backstage.
On both days, different SMTown artists have attended such as BoA, Super Junior’s Eunhyuk, Girls’ Generation’s Taeyeon and Hyoyeon, SHINee’s Minho, Red Velvet, NCT, and SM male trainees as well as Lee Sooman
On Keyword#BoA EP 57 on V LIVE, both of BoA and Lee Soogeun mentioned Yunho and others such as Minho for their good nature~ ^^
They also mentioned that Yunho was one of the celebrity who stayed late at sm party last year and BoA talked about their arrangement into a drinking group and a talking group, and how she is closer to Yunho~
