They have this formation where the order is 💚💜❤️💛💙. They had it for a really long time now. So 💛 is always stuck between ❤️ and 💙. I feel that Seulgi is feeling left out coz it's always been the 3 of them. But during the Reve Festival Trilogy, WenRene's been stepping up on clinginess. I'd never thought Wendy would step forward like that just to be near Irene in 2:35. Wendy is the person who would just want be on the sides like she's not worthy to be anywhere near the center. That's why while ReVeluvs arrange hearts by age ❤️💛💙💚💜, she would arrange it like this 💚💜💖💛💙 just like they're arrangement on interviews etc. (Look at Irene's heart... 🤣🤣🤣 Whipped)
