''Haahhh… Haaahhh…'' Isaac's face was drooping with tiny beads of sweat trickling down his face.
''Here.'' Sebastian stopped in front of him and offered a water bottle.
''T-Thanks…'' Isaac took it with gratitude, and once he took off the cap, he started gulping down the cold water.
''Haahh…'' He wiped his lips and looked much more refreshed.
''How long have you been exercising?'' Sebastian asked while still remembering the previous scene and was sure that it was impossible to achieve in a year, but seeing Isaac's somewhat skinny body, he felt curious.
''6 to 7 years, I guess,'' Isaac replied and took another sip of the water.
''What?!'' Sebastian widened his eyes in shock. He didn't expect that kind of answer.
Isaac wryly smiled and said, ''Yeah… I know.''
''How?'' Sebastian was truly curious how Isaac's body still looked like that!
He shrugged and replied, ''No idea.''
''Have you visited a hospital?'' Sebastian asked with concern, ''That can't be normal.''
