In terms of age in BTS, SUGA is only behind Jin, so it's not surprising that the other younger siblings in the group have to respect him. But in reality, SUGA has a "power" that even Jin must be wary of and other members of the group do not dare to violate.
Even though he is extremely kind and sweet on the inside, SUGA has a real authority when he forbids the members from doing this. Even BTS members sometimes don't dare to break the rules if they don't want to be scolded by him.
Below is SUGA's "power" demonstrated and the members' experiences when trying unsuccessfully to overcome his boundaries:
Everyone knows that RM is the leader of BTS while Jin is the eldest brother of the group and it seems that they are the two most powerful members in BTS. They are also said to be the most vocal in the group that any member must obey.
However, with his savage reputation, it is no surprise that SUGA is the choice of the majority of ARMYs for the candidate of the strictest and most powerful person in BTS. SUGA is a character who, although not the oldest or the leader of the group, makes all the other members wary when talking.
In particular, SUGA once showed his authority when he forbade BTS members to do this and even the other members of the group did not dare to violate: It was teasing SUGA or waking him up while he was sleeping.
Specifically, despite their close friendship and daily interactions, waking SUGA while he was resting was truly a nightmare that all members tried to avoid. Because interrupting SUGA's sleep is not a good thing unless you want to be ¢υяѕєd. Any member, even Jin, who tries to wake him up or tease him, will have to face extremely serious consequences.
Sometimes they get scolded by SUGA, sometimes they get ¢υяѕєd by him in unexpected situations. But of course, it's very funny and interesting!
In an old video, fans had to laugh when they saw the members' fearless attitude as they tiptoed forward to try to wake them up. But at the last minute, they regretted doing this when he truly exploded with his power.
At that time, j-hope did not dare to bother SUGA anymore and had to leave immediately because he did not want the situation to get worse.
In another case, when V and Jin were tasked with waking up SUGA and making him move, they also appeared apprehensive about performing this mission. V didn't even dare to do that while Jin tiptoed closer to SUGA, making Jungkook admire his brave action.
In the end, SUGA flatly rejected Jin and did not help him complete his mission. And just as j-hope predicted, it's hard to bother SUGA when he's sleeping.
But the reality is that in the years when BTS first debuted, SUGA was often so busy with work that he lacked sleep, so it seemed that during his rare breaks, he was petrified and didn't want to be bothered. Meanwhile, his reaction when the members tease him or try to wake him up seems to be just a way to create jokes and funny situations. But it also shows that SUGA has such incredible strength that the members and Jin have to be shy and respectful.
During the years when BTS first debuted, people often saw a genuine "tsundere" SUGA. A tsundere is the type of person who acts rude, cold, and hostile towards the person he loves to hide his warm and caring feelings. Of course, all the group members and fans understand that and even love his personality, which is why they often want to tease SUGA.
Over the years, the sharp corners of SUGA's personality have been eroded, SUGA has now become "calm" and warm, knowing how to express his feelings to those around him much better. But this also makes fans recall a part of his previous "fierce" but also "funny" personality and see how much he has changed!
