Just finished reading it. Just my opinion but i think ho was more mad at himself and is taking it out on sirang lol. Ho got angry mostly cause of how sirang was implying ho has romantic feelings for his friend since he keeps looking for him. In the end, he was just too embarrassed to admit that he likes sirang.
Owhh Ho just got excited when he knws sirang will be join them and he felt embarrassed the time he need to take sirang to their grp but whn sirang saw Ho wearing those short pants..that make him felt irritated maybe? I couldn't read his facethen sirang though Ho has a feeling to kyunghoon so he talk something tht make Ho angry and do you remember when Ho said he went for a walk when they eating in a grp.. There are two ppl tht run into sirang for help right, and that person hold sirang hand thats why Ho felt jealous then yeahh u knw the next story Emm i just telling u the way I understand this story heheh
Um I have alot of questions? What happens to the kyunghoon couple? What happens to the brother? Oh and in the extra story I didnt get why the hell ho was angry at sirang? Like I read it 5 times and I still don't get it? But whatever. Other than that great story <3
