During his 1 vs. 1 battle on 'Show Me The Money 5', Taewoon's shirt caught the judges attention after which Taewoon explained that the shirt had been made by fans after his overdone expressions from his previous appearance on season 4. 

Then on the June 8 airing of 'Welcome Show', fans spotted Zico wearing a matching shirt! When asked about the shirt during 'Welcome Show', Zico stated, "I think there are really good vibes around hyung right now. I want to absorb some of that from him, some of that positive energy, so I wore this shirt." 

Previously, Zico also showed support after the former SPEED member was eliminated on 'SMTM5' after being forced to participate in 4 rematches. Fans admired the brothers' close relationship, commenting, "They grew up so well," "They seem like such close brothers kekeke. Woo brother be more successful," "Taewoon could be really stressed out and even develop an inferiority complex because his younger brother has the same career path as him and is doing better, but he tries not to be phased by it and always just does what he wants to do positively, which is very admirable. I hope Woo Taewoon becomes successful too." 

The adorable childhood photo of the Woo brothers is a bonus!
