Recently, IU made an appearance at JTBC's 'Hyori's Homestay' and revealed her close relationship with actress Yoo In Na.
They are so close that they live in the same apartment building. IU also wrote a song about Yoo In Na, which was released on last year's April Fool's Day.
It is an acoustic guitar tune, and the lyrics reveals IU missing her one and only true best friend Yoo In Na.
According to a source, this song was created while IU was away from home, shooting for last year's SBS Drama 'Moon Lovers: Scarlet Heart Ryeo'.
For the drama, IU had to stay away from home for about one week and could not contact her best friend Yoo In Na.
This song was untitled until IU's 8th debut anniversary fan meeting.
IU and Yoo In Na, who are 11 years apart, first met in SBS variety show called 'Heroes' and are maintaining their friendship since then.
