Yeah his calmness is second to none. He doesn't even actually care about Megumi's father's approval. Tsugumi just cares about putting Megumi at ease, and Megumi's father's approval is important to Megumi, and what Megumi cares about, Tsugumi decides also to care about. Tsugumi is rather impressive.
Tsugumi has always been impressive since chapter 1 Imo he's the very best omega character ever created in the omegaverse world, he is just himself no matter his traits are, and what matters the most to him rn is megumi and their future which I think is freaking adorableee
Tsugumi being the calm one in this chapter is horrifying LMAO Go get em tsugumi, make the old man eat his own words! fuck that guy!!
