Lee Taehyun (Blue) (99′) + Chinda Apibal (Ace) (98′)
Relationship name: Blue Ace
During early trainee days, Ace became friends with Mija thanks to their ages (98 liners), then also Blue became friends with Mija.
Both Taehyun and Chinda wanted to be friends with the other and they both told Mija about it.
Chinda liked Taehyun's cuteness and she found her mysterious.
Taehyun thought how funny and energetic Chinda is.
Mija kind of brought them together by inviting them three to eat lunch together and similar things. Finally, they all got to practice togher due to them all being rappers and possible band mates.
When Mija got ill during trainee days, Taehyun and Chinda practiced rapping without her and that made them even closer.
When they didn't have anything to do, they both usually volunteered to clean the dorms to help their eonnies, but the eonnies always insisted on following the cleaning plan which was fair to all, so Blue Ace stopped volunteering. Later on, they both got very busy with writing songs, rapping, dancing and singing. Sometimes they were so tired that they fell asleep, so Lia and Dahee secretly took their shift, because they were both only vocals (and occasional dancers) and had less work to do.
They're both very complicated people with many sides of them, so their relationship is very complex too, they have many ways to act to each other.
For example they fight ironically and tease each other, but can switch to being extra nice, caring and cuddly in a matter of seconds.
They used to fight a lot when they were younger, it always begun with blaming each other, then they suddenly started laughing and said they were sorry. Now they're more mature, they don't blame others that often and they fight rarely.
Very honest with each other. They tell each other everything and they’re there for each other in the darkest of days.
They often act like little children when they're together, for example they once took a challenge that they'll walk with connected legs all day (except practice). In CE building, they met Bin Haneul (the CEO of Cloud Entertainment) on the stairs and fell in front of her. It was very embarrassing but she asked them if they were okay and warned them that they shouldn't do that because they'll get hurt. Then she laughed and stepped over them.
They understand the each other the most. If anything happens, Blue is the first person Ace goes to and vice versa.
They started calling each other soulmates the fourth year after debut.
They're the ultimate best friends of Butterfly.
