Love (How do they show love physically, verbally, etc.?)
Our resident salt mine struggles with revealing the more tender emotions. Not because he doesn’t feel them, oh no, but because he guards his heart so much. Who wouldn’t after being lied to by someone they looked up to?
But in recent time, that wound (and the brothers’ relationship) has healed to a degree meaning Tsukishima is getting better about showing love.
It comes in stages, starting with compliments that become less and less back handed.
Physical love, at least in private, he’s comfortable with a lot quicker than anticipated. The first time you came over to watch a movie after getting together with him, he shocked you by pulling you flush against his side, arm draped over your shoulder.
